Washington: United States President Donald Trump has been dismissing the protests against his presidency and demonstrations at congressional town hall meetings across the country as concocted by his political enemies. But now he has an alleged culprit: Barack Obama.

In an interview on Monday with Fox News Channel, Mr Trump said that he believes his predecessor is helping to organise the protests.

"I think that President Obama is behind it because his people certainly are behind it," Mr Trump said. "In terms of him being behind things, that's politics. It will probably continue."

Mr Trump made his comments during an interview at the White House with Fox & Friends anchors Steve Doocy, Brian Kilmeade and Ainsley Earhardt. The interview aired on Tuesday morning, in advance of Mr Trump's formal address to a joint session of Congress.
