"I think that President Obama is behind it because his people certainly are behind it," Trump said. "In terms of him being behind things, that's politics. It will probably continue."
Trump made his comments during an interview at the White House with "Fox & Friends" anchors Steve Doocy, Brian Kilmeade and Ainsley Earhardt. Most of the interview will air Tuesday morning, in advance of Trump's formal address to a joint session of Congress, but Fox released an excerpt Monday of his remarks about Obama.
In the interview, one of the Fox trio told Trump that Obama's political group — presumably Organizing for Action, the successor group to Obama's campaigns — was helping to organize activists to demonstrate, and asked the president whether he suspected Obama himself was behind the efforts.
“I think he is behind it," Trump said. "I also think it’s politics. That’s the way it is.”
A spokesman for Obama did not immediately reply to a request for comment.
Trump has lambasted the town-hall demonstrators on social media, tweeting last week that they were "so-called angry crowds" and that the demonstrations were "planned out by liberal activists."
In the interview, Trump offered high marks for his accomplishments in the White House, but he gave himself a “C” for messaging, conceding that he has not been able to properly explain what he's done.
In terms of messaging, I would give myself a C or a C plus,” Trump said. “In terms of achievement, I think I'd give myself an A. Because I think I've done great things, but I don't think I have — I and my people, I don't think we've explained it well enough to the American public.”
