FIRST ON FOX: Democratic Maine Senate candidate Graham Platner's deleted Reddit account reveals graphic posts about masturbating in portable toilets and praising explicit military restroom graffiti — the latest in a growing trail of vulgar comments that could define his race against Susan Collins. Platner has dismissed past controversies as 'joking' and 's***posting,' but GOP strategists say the pattern raises fundamental questions about his judgment and fitness for office. He became Democrats' presumptive nominee after Gov. Janet Mills dropped out last month.
