Several House Republicans were caught by surprise when GOP leaders announced they would postpone sending articles of impeachment against Homeland Security Secretary Alejandro Mayorkas to the Senate, including those preparing to lead the prosecution in the trial. 

The House was initially scheduled to send the articles of impeachment to the upper chamber on Wednesday evening, which would have triggered the beginning of the trial on Thursday morning. However, those plans were abruptly changed on Tuesday afternoon after several GOP senators requested House Speaker Mike Johnson (R-LA) to delay the transfer, catching some House Republicans off guard.
