HOUSE OVERSIGHT 030327 Political experts told The Oregonian on Tuesday that Roberts' reply completely railroaded his chances of unseating Walden in a race that was already said to be a longshot. "If he wins, I'll sell my house and donate to charity," joked Jim Moore, political science professor at Pacific University. Roberts is apparently known for making crude and outlandish remarks on Twitter, most of which have been aimed at politicians. "#NikkiHaley very hot," he once tweeted, in reference to a TV appearance she made last year. "Important stuff," Roberts added. Describing Illinois Democratic Sen. Kamala Harris, the independent candidate tweeted: "Hot, tough & smart!" Commenting on a video featuring President Trump, he said: "It looks like he's morphing into a woman, get that man a haircut and non fat chocolate cake!" In response to the social media backlash he's been receiving, Roberts refused to apologize and instead cited the Constitution. "It's that whole 1st amendment thing," he tweeted on Tuesday, along with an official explanation from Twitter as to why his tweet about Melania hasn't been taken down. "We have investigated the reported content and could not identify any violations," a spokesperson said. "Accordingly, we have not taken any action at this time."
