"I think what is clear in the Senate is that there will be enough votes to pass the resolution of disapproval, which will then be vetoed by the president and then in all likelihood the veto will be upheld in the House," McConnell said while speaking to reporters in Kentucky.

The Senate will vote on the resolution before lawmakers leave town on March 15 for a weeklong recess.

Trump announced that he would declare a national emergency to build the U.S.-Mexico border wall after Congress passed a funding bill that included $1.3 billion for physical barriers, below the $5.7 billion the president requested.

But his decision has put Republicans in a bind. GOP senators have been wary of breaking with the president on border security, but they've also been concerned that Trump's decision could let a future Democratic president use a national emergency declaration on issues like climate change.

McConnell added that while he was supporting Trump's emergency declaration, he was "hoping he wouldn't take that particular path."

"Yeah I am," he said, asked if he was concerned about the precedent set for a Democratic president. "That's one reason I argued obviously without success to the president that he not take this route."
