Former national security adviser John Bolton wrote in a new book manuscript that President Donald Trump directed the withholding of military aid to Ukraine.

About 72% agreed that the trial "should allow witnesses with firsthand knowledge of the impeachment charges to testify."

"Witnesses should have something to do with and direct knowledge of the charges against the president."
