Sen. Tim Kaine, D-Va., wants Congress to take a more active role as a check on the Trump administration’s use of military force following the surprise weekend operation in Venezuela, and he plans to force a vote on legislation that would halt further military action in the country without lawmakers’ approval.

Kaine joined a chorus of congressional Democrats who were frustrated at President Donald Trump’s decision to strike Venezuela’s capital of Caracas, and subsequent capture of Venezuelan President Nicolás Maduro and his wife without oversight or approval from Congress.

Congressional Democrats have long been frustrated at Congress’ diminished role in decision-making since Trump took office last year, particularly over continued strikes in the Caribbean ahead of Operation Absolute Resolve on Saturday.

Kaine argued on a call with reporters that Congress has the constitutional authority to weigh in on military action and was frustrated throughout Trump’s second term that the check and balance was being bowled over.

‘It’s time for Congress to get its a– off the couch and do what the Constitution mandates that we do — the Constitution we take an oath to,’ Kaine said over the weekend. ‘We have to put this before the American people, not just in private settings, but in public hearings by the key oversight committees, Intelligence, Armed Services, Foreign Relations in both houses, and explore whether the United States should enter into yet another war with unforeseen consequences.’

Kaine again plans to bring a war powers resolution for a vote in the Senate, which is expected to come to the floor this week.

It’s not the first time he has tried to reassert Congress’ authority when it comes to the administration’s use of military action. Kaine earlier this year forced a vote on a war powers resolution following Trump’s strike on Iranian nuclear facilities. That resolution failed on a largely party-line vote, save for Sen. Rand Paul, R-Ky., who joined all Senate Democrats in support.

The Virginia Democrat’s latest effort would prevent further military action in Venezuela without congressional approval.

Senate Minority Leader Chuck Schumer, D-N.Y., who is a co-sponsor on the latest war powers resolution along with Kaine and Paul, said he would ensure the measure would get ‘adequate floor time so we could debate and discuss this.’

Schumer is also pushing for hearings to investigate the strikes and capture of Maduro and noted that he spoke with top Democrats on several committees who contended their Republican colleagues ‘have expressed a lot of troublesome comments about what Trump is doing and the way he is doing it.’

‘We’re going to be pushing our Republican colleagues to stand up for the American people, to get this done,’ Schumer said. ‘Congress should not be sidelined as the Trump administration gets sucked into another nation-building quagmire, and we’re going to hold them accountable, protect American lives, to protect America’s interests.’

Another issue that many congressional Democrats have is that lawmakers weren’t notified of the strikes until after the fact. Secretary of State Marco Rubio argued over the weekend that it would have been risky to notify lawmakers in advance given the sensitive nature of the operation. Trump charged that Congress was kept in the dark because lawmakers leak. 

Senate Majority Leader John Thune, R-S.D., who didn’t receive notification of the operation until afterward, said that he was ‘comfortable’ with the timing. 

‘They didn’t tell me ahead of time,’ Thune said. ‘But I think there’s a reason why, like I said, before notification of Congress in advance of really critical and hypersensitive missions, to me, seems ill-advised anyway.’
