House Republicans are expected to deliver the articles Tuesday, jump-starting impeachment proceedings that will bring unprecedented questions of process to the Senate.
DHS Secretary Alejandro Mayorkas will testify before the House Appropriations committee on the department's budget, as Congress waits for House Speaker Mike Johnson to deliver articles of impeachment to the Senate against the secretary.
Republican senators requested more time Tuesday to build a case for a full trial. The sudden change of plans cast fresh doubts on the proceedings, the historic first impeachment of a Cabinet secretary in roughly 150 years.
The Republican-controlled House impeached Mayorkas Feb. 13 over the Biden administration's handling of the U.S.-Mexico border. Senate leaders have shown little interest in spending much time on it.
Focused on border security, Republicans in the House argue that Mayorkas has "refused to comply" with immigration laws resulting in the record surge of immigrants at the U.S.-Mexico border and "breached the public trust."
Mayorkas has been meeting with senators on a border security package and argues the Republicans should instead be working with the Biden administration on U.S.-Mexico border issues.
