Senator Schumer will make a motion to dismiss the articles of impeachment levied against the homeland security secretary, Alejandro Mayorkas, shortly after senators are sworn in as jurors for the secretary’s trial for malpractice in border policy and lying. Republicans have warned the New York lawmaker that he would be setting a dangerous precedent by refusing to hold a trial. 

If Mr. Schumer does so and a simple majority of the Senate agrees, it will be the first time in American history that an impeachment trial is tabled before it even begins. Mr. Schumer’s strategy was first reported by Axios.
