The Democratic-controlled Senate quickly dismissed the impeachment charges brought by the U.S. House against Homeland Security Secretary Alejandro Mayorkas. The Senate voted to rule both impeachment articles unconstitutional because they did not rise to the level of “high crimes and misdemeanors.”

Senate Republicans raised several motions to try and kick off a lengthy trial but they all failed along party lines.

The move by the upper chamber caps a months-long effort by Republicans to oust Mayorkas over his handling of the U.S.-Mexico border. Senate Majority Leader Chuck Schumer accused Republicans of trying to impeach the secretary over policy disagreements. Senate Minority Leader Mitch McConnell said the dismissal sets a dangerous precedent.

A White House spokesperson said Wednesday that the Senate has “rightly voted down this baseless impeachment that even conservative legal scholars said was unconstitutional.”
