Donald Trump’s ex-national security adviser John Bolton has said he will testify at the president’s Senate impeachment trial should he be subpoenaed to appear, prompting top Democrat Chuck Schumer to warn majority leader Mitch McConnell that preventing Bolton or other witnesses appearing would amount to “participating in a cover-up”.
But McConnell reportedly has votes to set Senate rules for the trial and forge ahead without witnesses.
As tensions with Iran continue to rage, Republican senator Rand Paul has said the president “got bad advice” on his decision to have Quds commander Qassem Soleimani assassinated at Baghdad International Airport on Friday in a US airstrike.
The president told reporters that the administration will debrief members of Congress about its intelligence and what it believes General Soleimani was planning before the presidents' supposedly preemptive attack.
Mr Trump didn't clarify whether he will target Iranian cultural sites following any retaliatory attack, though Secretary of State Mike Pompeo appeared to walk back the administrations' threat.
The president told reporters: "I like to obey the law. But think of it: They kill our people, they blow up our people and then we have to be very gentle with their cultural institutions. But I'm OK with it. It's OK with me. I will say this, if Iran does anything that they shouldn't be doing, they're going to be suffering the consequences and very strongly."
Trump critic and broadcaster Joe Scarborough has meanwhile written an op-ed for The Washington Post accusing the president of governing according to “a collection of scattered grievances, emotional impulses and random tweets”.
Read live coverage as it happened:
Donald Trump’s ex-national security adviser John Bolton has said he will testify at the president’s upcoming Senate impeachment trial should he be subpoenaed to appear, prompting top Democrat Chuck Schumer to warn majority leader Mitch McConnell that preventing Bolton or other witnesses appearing would amount to “participating in a cover-up” (an argument also made by House speaker Nancy Pelosi).
"I think this president has pushed this to the limit with action that has a huge, escalating effect," says Scott Anderson, a former attorney in the State Department's legal office and former legal adviser for the US embassy in Baghdad. "Maybe this will push Congress to make it a priority. ... Anything short of legislative action doesn't mean anything."
The showdown between the White House and Capitol Hill provides the latest example of how Trump's willingness to break the norms in Washington is setting new standards in governance. Ahead of the attack that killed the general, the president did not consult with congressional leaders. In the aftermath, he refused to make public his justification for the airstrikes. Facing an outcry, Trump scoffed that his tweets should provide adequate updates to Congress, regardless of what is required by law.
McConnell said on Monday there's plenty of time for lawmakers to learn more about the president's reasoning for the attack. He complained that Democrats "rushed to blame our own government before even knowing the facts, rushed to downplay Soleimani's evil while presenting our own president as the villain."
But as Schumer argued on Monday, "It is essential for Congress to put a check on this president."
Past presidents at least signaled a nod to the legislative branch, which has the sole power under the Constitution to declare war, knowing they would need to ask Congress to pay for military operations. It's one way the founders sought to keep the executive in check.
But Congress has allowed its role to erode since the passage of Authorisation for Use of Military Force (AUMF) in 2001 to fight terrorism after the 9/11 attacks and passage of another AUMF for the invasion of Iraq in 2002.
The fallout from those votes has deeply divided Congress and the nation, with many lawmakers, particularly Democrats, now saying they were mistakes. Yet lawmakers have been paralyzed on the question of whether to repeal or change those authorities.
Only after US-based journalist Jamal Khashoggi was killed last summer in a gruesome murder at the Saudi Arabian consulate in Turkey did Congress muster the resolve to slap restrictions on American involvement with the Saudi-led war in Yemen. It was a rare exertion of authority from Congress, the first since the passage of the War Powers Act of 1973. And Trump promptly vetoed it.
"There's no question the president has gotten stronger over time, the Congress less strong," said Wendy Sherman, a former undersecretary of state in the Obama administration and chief negotiator of the Iran nuclear deal. This is a president who we know makes decisions by impulse and without any deliberative process," said Sherman, who now directs the Center for Public Leadership at Harvard's Kennedy School. "Ceding all this power to an impulsive president... puts our national security at risk."
General Mark Milley, chairman of the Joint Chiefs of Staff, told reporters the US is "moving forces around" Iraq and neighbouring Kuwait. He said a draft letter circulated internally by a US Marine commander was a "poorly written" honest mistake that should never have got out.

Gen Milley and defence secretary Mark Esper said the US has been repositioning troops, largely due to increased security threats from Iran. The letter was meant to co-ordinate with the Iraqi military on an increase in US helicopter and troop movements as they shift positions around the country. "There's been no decision whatsoever to leave Iraq," Esper said. "There's no decision to leave, nor did we issue any plans to leave or prepare to leave."
Gen Milley acknowledged that some language in the letter "implies withdrawal" but that "is not what is happening".
Iraq's UN ambassador Mohammed Hussein Bahr Aluloom issued a letter to the security council on Monday, calling the airstrike "a dangerous escalation that might ignite a devastating war in Iraq, the region and the world". He also urged the council to hold accountable "those who have committed such violations".
Esper said the US remains committed to the campaign to defeat Isis in Iraq and the wider region. Any Security Council action sought by Iraq against the Trump administration, however, is virtually certain to be vetoed by the US.
Paul Gosar, member of Congress for Arizona, tweeted the fake photo with the caption “The world is a better place without these guys in power” in a series of posts about the killing of General Soleimani.
The Justice Department plans to pursue the death penalty for a member of the MS-13 gang accused in the kidnappings and killings of two Virginia teenagers in 2016, a move that comes as the Trump administration fights to restart federal executions.
The president will travel to Wildwood, New Jersey, in Van Drew's district on 28 January to hold a rally, his campaign announced.
Trump endorsed the Democrat-turned-Republican during an Oval Office meeting on 19 December, when Van Drew formally announced he was leaving the Democratic Party after providing Trump with a symbolic victory in the prior day's impeachment vote. Van Drew bucked Democrats to join a united Republican Party in opposing impeachment.
Van Drew said at the time that he believed the GOP was a "better fit" and promised Trump his "undying support." Trump promised to return the favour and announced that he was endorsing Van Drew for re-election and labeled him "a tremendous asset for the party."
Van Drew had been facing an uphill Democratic primary battle, including a challenge from Brigid Harrison, a Montclair State University political science professor who had secured the backing of top local Democrats, including the New Jersey Senate president.
