WASHINGTON (Reuters) – President Donald Trump’s fellow Republicans in the U.S. Senate came under fresh pressure on Monday to allow witnesses and new documents in his impeachment trial, while Trump’s defense team argued that policy differences were a crucial reason that Democrats have sought to remove him from office.
A New York Times report that former national security adviser John Bolton has written in an unpublished book manuscript that Trump told him he wanted to freeze security aid to Ukraine until Kiev helped with politically beneficial investigations prompted fresh calls by Democrats for Bolton and other witnesses to testify at the trial.
Republican Senator Mitt Romney, a sometime critic of Trump, said there was a growing likelihood that at least four Republican senators would vote to call for Bolton to testify, which would give Democrats the votes necessary to summon the former national security adviser.
Senate Republicans so far have refused to allow any witnesses or new evidence in the trial that will determine whether Trump is removed from office. Trump’s legal team on Monday resumed its presentation of opening arguments in the trial, including remarks by Ken Starr, the former independent counsel whose investigation paved the way for the impeachment of former President Bill Clinton, a Democrat, in 1998.
