On Thursday, Kentucky Sen. Paul became the lone holdout against a bipartisan effort to approve $40 billion in aid to Ukraine.

The effort supported by both Senate Majority Leader Chuck Schumer and Senate Minority LeaderMitch McConnell, blocking the unanimous vote they needed to quickly approve the funding, was objected to by Paul.

Paul asked that the bill be debated and subjected to a 60-vote threshold, and that an inspector general be installed to oversee the spending of the money.

Paul said that his oath of office was to the national security of the United States of America.

In contrast to McConnell's statement in the Senate, Paul's objection stood in stark contrast.

Ukraine is not asking us to fight. They are only asking for the resources they need to defend themselves. McConnell said they need this help right now.

Schumer called for the Senate to quickly move on the matter, saying it was a moral obligation to help Ukraine fight Putin.

The package is ready to leave. Schumer said that the majority of senators on both sides of the aisle want it.

Schumer said he thought it was clear from Paul's remarks that he didn't want to aid Ukraine.

He will only delay desperately needed Ukraine aid.

The Senate will vote on the bill late Monday afternoon.

The bill that Paul objected to was passed by the House. Lawmakers added another $7 billion to the $33 billion in aid that President Joe Biden requested.

Paul doubled down on his stance on Thursday.

My oath of office is to the US Constitution. There is no oversight included into how the money is being spent, and Congress is trying to ram through a spending bill that I doubt anyone has actually read.

While I sympathize with the people of Ukraine, and commend their fight against Putin, we cannot continue to spend money we don't have.
