WASHINGTON (Reuters) - President Donald Trump would have a tough time blocking John Bolton's testimony in his U.S. Senate impeachment trial by invoking the legal doctrine called executive privilege if his former national security adviser is subpoenaed as a witness, according to legal experts.
The Republican-controlled Senate has not yet decided whether to allow any witnesses or new evidence in the trial that will determine whether the Republican president is removed from office after being impeached on Dec. 18 by the Democratic-led House of Representatives on two charges.
