MyPillow CEO Mike Lindell was permanently banned from Twitter on Monday night for "repeated violations of our Civic Integrity Policy," a Twitter spokesperson told CNN.

Between the lines: Dominion Voting Systems has threatened to take legal action on Lindell over his spread of misinformation related to the 2020 election. The ban comes as he weighs a run for governor of Minnesota.

Donald Trump was eclipsed in media attention last week by President Biden for the first time since Trump took office, according to viewership data on the internet, on social media and on cable news.

Why it matters: After Trump crowded out nearly every other news figure and topic for five years, momentum of the new administration took hold last week and the former president retreated, partly by choice and partly by being forced off the big platforms.

Some blue-chip corporate clients have cut the cord with lobbying firms that monetized their close relationships with Donald Trump and his administration, new disclosure filings show.

Why it matters: Every change in administration shuffles the groups that can influence decision-makers — and who have the ability to market that access to high-paying clients. A raft of lobbying agreement terminations since Trump lost reelection in November indicates segments of corporate America are tweaking their advocacy strategies accordingly.

President Biden told CNN Monday that he believes the impeachment trial of former President Trump "has to happen," but he does not think 17 Republicans will join Democrats to vote to convict.

Why it matters: Biden's comments are most concrete he has made about his views on Trump's second impeachment.

House managers on Monday delivered the article of impeachment against former President Trump for "incitement of insurrection" to the Senate.

Why it matters: The expected move formally triggers preparations for the trial. Senate Majority Leader Chuck Schumer announced last week that the trial will begin the week of Feb. 8.

Sen. Patrick Leahy (D-Vt.) is expected to preside over former President Trump's second impeachment trial, a Senate source tells Axios. CNN first reported Leahy's role.

Why it matters: The Constitution requires the chief justice of the Supreme Court to preside over a sitting president's impeachment trial rather than the vice president — who has the title of president of the Senate — to avoid a potential conflict of interest. However, there is no precedent for a former president.

The Justice Department's inspector general will investigate whether any current or former DOJ officials "engaged in an improper attempt to have DOJ seek to alter the outcome" of the 2020 election, the agency announced Monday.

Driving the news: The investigation comes in the wake of a New York Times report that alleged Jeffrey Clark, the head of DOJ's civil division, had plotted with President Trump to oust acting Attorney General Jeffery Rosen in a scheme to overturn the election results in Georgia.

The Supreme Court on Monday ordered lower courts to dismiss two cases that alleged former President Donald Trump unlawfully profited from his businesses while in office, in violation of the Constitution's emoluments clauses.

The big picture: Both sides agreed the issue had become moot after Trump's term finished on Jan. 20, according to Bloomberg, ending a prolonged legal battle that extended for most of his presidency.

The will-he-or-won't-he speculation surrounding a possible gubernatorial run by MyPillow CEO Mike Lindell is destined to continue at least a bit longer.

What he's saying: Lindell told Axios that his focus is currently on proving his (baseless) claims of election fraud. He won't make a decision until that fight is resolved.

In this episode of How It Happened: Trump's Last Stand, national political correspondent Jonathan Swan traces how Donald Trump's strategy to dispute the result of the 2020 election evolved from targeted lawsuits to embracing — and amplifying — conspiracy theories.

• Starting with the Four Seasons Total Landscaping press conference and digging into subsequent meetings, Swan offers new reporting on how Rudy Guliani and Sidney Powell became the faces of Trump's legal strategy.
• Swan's reporting takes listeners behind closed doors, where President Trump's inner circle and a group of conspiracy theorists clashed over how best to advise the president.
