The Senate agreed the move unanimously after the president’s criticism of the attorney general, Jeff Sessions, raised concerns he might be sacked soon.
The Senate will convene for pro forma sessions every three days until September. The Hill news outlet reported such meetings typically last for about a minute.
Trump has openly criticized Sessions in a series of Twitter statements in the recent days after the chief prosecutor recused himself from a Justice Department probe into alleged Russian meddling in the 2016 US election.
Trump also bashed him for not firing several top Justice Department officials and not pursuing a criminal investigation of defeated presidential candidate Hillary Clinton.
