Gordon Humphrey told New Hampshire lawmakers in a letter that has been widely shared that they should back his bid to dump Trump.

In a letter sent to Representative Annie Kuster, Humphrey urges her to back a bill that would set up an Oversight Commission on Presidential Capacity to decide whether Trump is fit for office.

“Donald Trump is seriously sick. He is dangerous,” read Humphrey’s letter, which he shared with news station WMUR on Wednesday.
