Robert F. Kennedy Jr. was challenged over whether he would work to remove Donald Trump from office if the president were found unfit to serve amid questions about his mental health. The exchange on Capitol Hill escalated to a yelling match with Kennedy insisting that the president was the "most sane" after a series of bizarre posts in recent weeks from the 79-year-old president, including comparing himself to Jesus and threatening to wipe out a civilization. "He's very, very sane," Kennedy insisted about Trump in a separate exchange later in the hearing. According to a new book on the health and human services secretary, Kennedy wrote a diary entry about stopping his car on a New York highway in 2001 and cutting the penis from a roadkill raccoon while his children sat in the back.
