The Senate on Wednesday voted to dismiss two articles of impeachment against Department of Homeland Security Secretary Alejandro Mayorkas, which allege he mismanaged an influx of migrants at the U.S.-Mexico border. Both votes were along party lines.

The impeachment trial of the first sitting Cabinet secretary came to a close a little over three hours after it started after Republicans quickly quashed an opportunity for limited debate and the creation of an impeachment committee, marking a rapid close to the first impeachment of a sitting cabinet secretary.

Democrats, voting along party lines, found the first article charging Mayorkas with “willful and systemic refusal to comply with the law" to be unconstitutional. Sen. Lisa Murkowski, R-Alaska, voted present. Democrats voted again along party lines, finding the second article charging Mayorkas with “breach of public trust” also to be unconstitutional. The trial came to a conclusion before the House impeachment managers could present their argument.

Shortly after opening the trial, Senate Majority Schumer, D-N.Y., offered Republicans a period of debate time and the opportunity to create an impeachment committee, which was sharply rejected by Sen. Eric Schmitt, R-Missouri. Schumer swiftly responded with a point of order to declare the first article of impeachment against Mayorkas unconstitutional, prompting the first of several procedural objections by Republicans that followed.

Sen. Ted Cruz, R-Texas, called to move the Senate to a closed session; Sen. John Kennedy, R-La., motioned to adjourn the Senate until April 30; and Senate Minority Leader Mitch McConnell, R-Ky., called to table the point of order made by Schumer. Each objection made by Republicans, who are in a relatively powerless position in the minority, failed.

Some senators appeared bored at their small desks as Republicans made procedural point after procedural point, forcing a series of failed votes to delay the trial and other matters. At times, Republicans attempted to deliver extended remarks on the House floor, blaming Mayorkas and Democrats for the record-breaking levels of migration at the southern U.S. border. Sen. Patty Murray, D-Wash., repeatedly interceded as her GOP colleagues tried to make their points of order into political statements, interrupting Sen. John Thune, R-S.D., as he described the border crisis in a long winded introduction to another failed procedural vote.
