Donald Trump

As President Trump continues to contest the results of the election, President-elect Joe Biden continues to shape his administration, which will take office on Jan. 20. But there is still no formal transition underway, a far cry from the last several times new presidents have taken power.

In 2009, just before then-President-elect Barack Obama was to deliver his inaugural address, members of the outgoing Bush administration's national security team sat down with the people who were about to take their place.

Richard Pilger resigned as head of the Justice Department's election crimes branch Monday night, protesting Attorney General William Barr's memo authorizing federal prosecutors to pursue allegations of voting irregularities.

Barr's policy is seen as a step toward validating President Trump's baseless attacks on the integrity of an election in which he has been declared the loser.

Despite calls from many for a concession this weekend, President Trump and his campaign say they are pushing on to fight the election results tooth-and-nail.

Practically speaking, that means lawsuits.

"Our campaign will start prosecuting our case in court to ensure election laws are fully upheld and the rightful winner is seated," Trump said in a statement Saturday. "The American People are entitled to an honest election: that means counting all legal ballots, and not counting any illegal ballots."

Defense Secretary Mark Esper has been "terminated," President Trump wrote in a tweet, and will be replaced by Christopher C. Miller, the director of the National Counterterrorism Center.

"Chris will do a GREAT job," Trump tweeted shortly after noon. "Mark Esper has been terminated. I would like to thank him for his service."

Sources say Esper already had a resignation letter ready to go — because Trump threatened to fire him in June over a disagreement about using active duty troops to quell street protests — and had recently updated it.

President Trump's campaign has unleashed a multipronged legal offensive directed at states where vote counting continued Thursday based on unsupported allegations about fraud and irregularities in the election.

Attorneys for the Trump campaign sought intervention from the U.S. Supreme Court and also filed suit in Pennsylvania, Georgia and Nevada seeking remedies they hoped would help their prospects in those places. In some instances, that included requests for counting to cease altogether or at least pause for a time.

In the final stretch of a tough reelection campaign, a president who burst into public consciousness as a media sensation has returned to the warm embrace of conservative media outlets and their stars.

And they have been returning the favor: giving airtime to President Trump and broadcasting his rallies, and hammering Democratic presidential nominee Joe Biden, his family and his allies.

President Trump is celebrating a caravan of supporters who followed a Biden-Harris campaign bus in Central Texas.

In a Saturday night tweet, the president retweeted a video showing his supporters surrounding the bus, set to Tech N9ne's "Red Kingdom." "I LOVE TEXAS!" Trump said.

Three civil rights groups filed a federal class-action lawsuit Thursday challenging the Trump administration's recent crackdown on diversity training.

When then-presidential candidate Donald Trump spoke in Manchester, N.H., a week before the 2016 election, he said the opioid crisis was destroying lives and shattering families.

"We are going to stop the inflow of drugs into New Hampshire and into our country 100%," Trump promised.

It was a major campaign issue. Overdoses were surging in battleground states key to the election, like New Hampshire, Ohio and Pennsylvania.

Miles Taylor, the former chief of staff at the Department of Homeland Security, has revealed himself to be "Anonymous," the author of a New York Times op-ed and book critical of the Trump presidency.

A federal judge has denied the Justice Department's attempt to intervene on President Trump's behalf in a defamation lawsuit filed by a woman who alleges he sexually assaulted her in the mid-1990s.

In her memoir published last year, writer E. Jean Carroll accused the president of raping her in the dressing room of a Manhattan department store more than two decades ago.

Trump denied the allegations and accused her of lying to sell books.

A second federal court has blocked the Trump administration's attempt to make an unprecedented change to who is counted in the census numbers that determine each state's share of seats in Congress.

A three-judge panel — which includes 9th Circuit Judge Richard Clifton, as well as U.S. District Judge Lucy Koh and Judge Edward Chen in Northern California — issued the new court order Thursday.

President Trump is racing from tarmac to tarmac in the final weeks of the campaign, holding large rallies to blast out an array of closing arguments — buckshot style — for a second term in office.

So far, most of the stops have been in swing states — Florida, Pennsylvania, North Carolina, Arizona, Wisconsin, Michigan and Nevada. But he has also held rallies in Iowa and Georgia, states he won easily in 2016 in a sign the electoral map has shifted on him.

President Trump, who has for months been at loggerheads with public health experts on how best to contain the coronavirus pandemic, on Monday called Dr. Anthony Fauci a "disaster" and complained that Americans are tired of hearing from "these idiots," according to media reports of a call between Trump and campaign staff.

The U.S. Supreme Court has agreed to a speedy review of President Trump's attempt to exclude unauthorized immigrants from the census numbers used to reallocate seats in Congress.

Republican Sen. Ben Sasse of Nebraska excoriated President Trump in a telephone town-hall meeting with constituents on Wednesday, saying the president badly mishandled the coronavirus pandemic, mistreats women and cozies up to dictators.

"I'm not at all apologetic for having fought for my values against his in places where I think his are deficient, not just for a Republican but for an American," Sasse said.

President Trump was back on the campaign trail on Monday, telling a packed outdoor rally in Florida that he feels "powerful" after his bout with the coronavirus.

Trump spoke for about an hour to an enthusiastic crowd, at an event that his campaign billed as the start of a breakneck stretch of travel leading up to the Nov. 3 election.

Trump stuck to much of his usual stump speech, but he did touch on the illness that led to him being hospitalized just over a week ago. He said he's feeling good now.

Members of Congress, advocacy groups and a former administration official say Operation Warp Speed should release its vaccine contracts with pharmaceutical companies, following an NPR report that the Trump administration awarded billions of dollars through a third party, bypassing the usual contracting process.

Soon after being discharged from the hospital for treatment for COVID-19, President Trump tweeted the slur "Chinese virus" to refer to the coronavirus, something he's often repeated during the pandemic.

It's the latest example of Trump's alarming language that critics charge is xenophobic, discriminatory and even white supremacist. While Trump denies those labels, he has increasingly returned to the issue of race in the runup to the November election.

President Trump's campaign is calling for next week's presidential debate to be held in person in Miami, despite the organizing commission's decision to hold it virtually.

Campaign manager Bill Stepien said Thursday night there is "no medical reason" why the debate should be shifted virtually. He cited a memo from White House physician Sean Conley, who said Trump would be safe for public events by Saturday.

White House chief of staff Mark Meadows said Wednesday that he and Treasury Secretary Steven Mnuchin are discussing potential stand-alone bills for aid to airlines, small businesses and Americans. He said the Trump administration was "still willing to be engaged" on piecemeal aid bills, though it was not optimistic about a comprehensive aid bill.

President Trump walked out of Walter Reed National Military Medical Center on Monday evening, planning on receiving the remainder of his treatment for COVID-19 at the White House.

He was seen pumping his fist in the air on the way out of the building and didn't respond to any questions from the press. Upon arriving back at the White House, Trump walked up the staircase of the South Portico entrance, removed his mask, gave reporters standing below a thumbs-up and saluted Marine One.

President Trump's medical team announced on Sunday that it had decided to treat the president with dexamethasone.

It was a decision that struck some doctors and COVID-19 specialists as surprising, given the fact that Dr. Sean Conley, the president's doctor, gave a fairly upbeat assessment of his patient's condition. Typically, only hospitalized COVID-19 patients in need of oxygen are given the drug.

With President Trump's announcement early Friday that he and the first lady have tested positive for the coronavirus, much of the focus inside the White House will likely turn to contact tracing.

A manager at McDonald's likely paid more federal income tax than President Trump did the year he took office.

The president's tax returns show he paid just $750 in federal income taxes each year in 2016 and 2017 and paid nothing at all for many years before that, according to reporting from The New York Times.

President Trump and first lady Melania Trump have tested positive for the coronavirus amid a busy week of events and during the height of the presidential campaign.

The president is expected to remain under watch of doctors at the White House but intends to continue carrying out his official duties.

In the first presidential debate, President Trump was asked if he would refrain from declaring victory until the election has been independently certified. He refused to make that commitment.

Atlantic writer Barton Gellman was not surprised.

President Trump attempted to clarify his position on white supremacists after a litany of members of his own party urged him to more clearly condemn the right wing group known as The Proud Boys, whom he told to "stand back and stand by" in Tuesday night's first presidential debate.

The president told reporters at the White House that he doesn't know who the Proud Boys are, but said they should "stand down" and let law enforcement do their work.

"I don't know who the Proud Boys are, you'll have to give me a definition," he said.

President Trump claimed to have the backing of the "Portland sheriff" during Tuesday night's debate with Democratic presidential nominee Joe Biden. But the sheriff of that jurisdiction in Oregon immediately responded by saying that's not true.

"As the Multnomah County Sheriff I have never supported Donald Trump and will never support him," said Mike Reese, in a tweet that was also shared by the Multnomah County Sheriff's Office.
