Bolton Says He Hopes White House Doesn't 'Suppress' His Book

In an interview, John Bolton expressed frustration over the White House's restrictions on his ability to speak publicly about his time there, while President Trump can tweet about him. Bolton hopes his experiences will be made public. His book, 'The Room Where It Happened,' is under review for containing classified information. The book reportedly claims Trump linked Ukraine aid to political investigations, a claim Trump denies. Bolton hinted at more details in his book and offered to testify in Trump's impeachment trial, but the Senate did not call witnesses and acquitted Trump.
