House Republican impeachment managers are set to send the Senate articles of impeachment against Homeland Security Secretary Alejandro Mayorkas on Tuesday after Senate conservatives successfully lobbied Speaker Mike Johnson (R-La.) to delay the delivery of the charges.

The transfer of the articles will officially force the Senate to take up the matter of impeachment against Mayorkas, which has been pending since the House approved the punishment in a 214-213 vote in February. Senators are expected to be sworn in as jurors Wednesday, with Senate President Pro Tempore Patty Murray (D-Wash.) presiding over the chamber.

Senate Majority Leader Chuck Schumer (D-N.Y.), however, is still expected to quickly move to table or dismiss the articles.

House Republicans are expected to read the articles at 2 p.m. EDT.
