U.S. Rep. John Larson announced Tuesday he has introduced articles of impeachment against President Donald Trump, following his escalating threats to end “a whole civilization” if Iran doesn’t comply with a deadline to reopen the Strait of Hormuz.

The Hartford-area congressman filed 13 articles of impeachment against Trump for high crimes and misdemeanors on Monday. They accuse the president, among other things, of circumventing Congress’ war powers regarding multiple military actions, the “militarization of domestic law enforcement” regarding National Guard deployments and his administration’s use of detention and deportations of “citizens or immigrants based significantly on race or ethnicity or political opposition.”

“Donald Trump has blown past every requirement to be removed from office. And it’s getting worse. His illegal war in Iran is not only driving up prices for American families — it has cost American lives,” Larson said in a statement.

“People across my district know he is unfit to lead and are calling for impeachment. While Republicans in the majority have so far failed to uphold their constitutional responsibility to initiate impeachment proceedings, that does not absolve others of their duty. Members of the Cabinet and those closest to the president can act immediately,” he added.

While more House Democrats are calling for Trump’s removal, especially in light of his comments about Iran, Larson is one of the few who have introduced articles of impeachment. His articles note they were drafted by Winsted consumer advocate and former presidential candidate Ralph Nader and constitutional lawyer Bruce Fein.

Since Republicans control the House, all of those impeachment efforts are highly unlikely to go anywhere. But Trump has previously warned Republicans as they head into the midterm elections in November that if they lose the House, Democrats will try to impeach him again.

Trump was impeached and acquitted twice during his first term. Larson and Connecticut’s all-Democratic delegation supported both impeachment efforts.

The White House called Larson’s impeachment resolution “pathetic.”

“Democrats have been talking about impeaching President Trump since before he was even sworn into office,” Davis Ingle, a White House spokesman, said in a statement. “The Democrats in Congress are deranged, weak, and ineffective, which is why their approval ratings are at historic lows.”

As he faces three challengers for the Democratic nomination, Larson has become increasingly vocal in his pushback against the Trump administration. When Kristi Noem was still leading the U.S. Department of Homeland Security, the congressman supported an effort to impeach her last year. She has since been fired as DHS secretary.

Larson also joined a growing chorus of Democratic lawmakers — including U.S. Sen. Chris Murphy — calling for Trump’s removal by invoking the 25th Amendment. That amendment allows for the temporary removal of presidents if the vice president and a majority of Cabinet members deem they are “unable to discharge the powers and duties of his office.”

One of Larson’s Democratic challengers, former Hartford Mayor Luke Bronin, has also called for Trump’s removal.

“After his sick Easter post, I called for impeachment or invocation of the 25th Amendment. When the President of the United States threatens to wipe out a ‘whole civilization’ because he doesn’t know how to get out of a reckless war that he recklessly started, morality, common-sense, and our national interest demand removal,” Bronin said in a statement.

Shortly before Trump’s Tuesday deadline approached for Iran to reopen the Strait of Hormuz, Trump backed off his threats to wipe out Iran’s “whole civilization” and announced that a ceasefire agreement was reached and the U.S. would refrain from attacks for the next two weeks.

“I agree to suspend the bombing and attack of Iran for a period of two weeks. This will be a double sided CEASEFIRE!” Trump posted on social media platform Truth Social about an hour and a half before the deadline. “Almost all of the various points of past contention have been agreed to between the United States and Iran, but a two week period will allow the Agreement to be finalized and consummated.”

But as the initial deadline loomed earlier on Tuesday, Connecticut’s congressional delegation sounded off about Trump’s rhetoric and his threats to “commit war crimes.”

“This is madness. This war is illegal and now Trump threatens war crimes and the eradication of an entire country if he doesn’t get his way,” U.S. Rep. Rosa DeLauro, D-3rd District, posted on X. “Congress must assert itself and rein in this president.”

Murphy, who has been a vocal antagonist of the president, was one of the first Democrats to call for the invocation of the 25th Amendment after Trump’s comments that “you’ll all be living in Hell” as he threatened to take out power plants and bridges on Tuesday.

“If I were in Trump’s Cabinet, I would spend Easter calling constitutional lawyers about the 25th Amendment,” Murphy posted on X over the weekend. “This is completely, utterly unhinged. He’s already killed thousands. He’s going to kill thousands more.”
