'None of This Is Legal... Trump Should Be Impeached': Will Congress Act Against Trump Lawlessness?

President Donald Trump's invasion of Venezuela is generating fresh calls for his impeachment and removal from office.

Shortly after the US military bombed the Venezuelan capital of Caracas and abducted Venezuelan President Nicolás Maduro and his wife, Cilia Flores, many experts on international law argued that the president's actions were completely illegal.

In an interview with the New Yorker's Isaac Chotiner, Yale Law School professor Oona Hathaway said that she didn't believe there "is a legal basis for what we’re seeing in Venezuela," while adding that the arguments the Trump administration will likely make simply "don't hold water."

For instance, Hathaway noted that while the United Nations charter allows nations to use military force in self-defense against military aggression, the administration's claims that attacking Maduro was a defensive measure intended to stop the flow of illegal drugs into the US was completely outside the scope of traditional self-defense.

"If drug trafficking is a reasonable justification, then a whole range of possible arguments can be made that basically mean that self-defense is no longer a real exception," she argued. "It’s the new rule. Why couldn’t you make the same argument about communicable diseases? There’s bird flu coming from a country, and therefore we have a legal justification for the use of military force. Once we start going down that road, the idea that there’s any limit evaporates."

Hathaway also said that Trump's militaristic ambitions seem to have grown throughout his second term, and she warned they could lead to a long and bloody US military occupation of Venezuela.

"In his press conference, Trump said that the United States would 'run the country,'" she said. "And he made it clear that he was not 'afraid' to put boots on the ground—for years, if necessary... it’s nothing like anything Trump has done before today. His previous illegal uses of force were all over shortly after they began. The scale of the operation that will be required is massive, and it means putting US soldiers at long-term risk."

Harvard Law School professor Jack Goldsmith wrote a lengthy analysis after the attack on Venezuela and also concluded that it violated the UN charter. What's more, Goldsmith argued that Trump's state plan to seize Venezuela's oil would likely run afoul of the Fourth Geneva Convention, which limits actions that occupying powers can take on the countries they are overseeing.

"There are a lot of international law rules and restrictions that purport to govern what the United States can do as an occupying power," he explained. "I don’t have space here to review them, but suffice it to say that these rules will touch on President Trump’s stated aim of 'tak[ing] back the oil' and 'get[ting] reimbursed.' We will see if the administration takes these rules seriously."

Many Trump critics also argued that, legality aside, toppling a foreign head of state and vowing to seize their nation's natural resources was morally wrong and deserving of impeachment.

"This is the behavior of a mob boss—but with nuclear weapons and the world's strongest military," argued Zeteo editor-in-chief Medhi Hassan. "None of this is legal. Trump should be impeached by Congress and indicted at The Hague."

Leah Greenberg, co-founder and co-executive director of Indivisible, denounced Trump's attack on Venezuela as "wildly illegal, immoral, and irresponsible," and urged the US Congress to exercise its powers to stop the president from further escalation.

"The power to declare war belongs to Congress and the American people," Greenberg said. "Trump has once again taken power that's not his. He is attempting to drag the country into war by decree, all while treating the presidency like a throne. Congress must act immediately to stop these illegal strikes and hold the Trump regime accountable. No Kings, No War."

Cavan Kharrazian, senior policy adviser for Demand Progress, demanded congressional action to "stop this reckless, unconstitutional act of war."

"We have seen what happens when the White House invents a pretext to launch a regime change war with an oil-rich nation: disaster and suffering for innocent civilians, our troops and their families, all while costing the American taxpayer a fortune as well," said Kharrazian. "Congress must do the right thing by voting to stop this obvious catastrophe."

Kat Abughazaleh, a Democratic candidate for US Congress in Illinois, wrote on Bluesky that the time for Democratic politicians to issue mealy-mouthed statements about Trump's actions was over.

"Democrats need to grow a fucking spine," she wrote. "No more strongly worded letters. It’s time to draft articles of impeachment. Impeach. Convict. Remove."

Rep. Ro Khanna (D-Calif.) also demanded that members of his party take a strong stance against Trump's illegal Venezuela attack.

"The silence from many media-hyped 2028 contenders today is shocking," he wrote on X. "If you cannot oppose this regime change war for oil, you don't have the moral clarity or guts to lead our party or nation."
