Former President Barack Obama reportedly told friends that President Trump is "nothing but a bullshitter" after an election night call with his successor.

Obama made the comment to friends after Trump unexpectedly talked about his "respect" for the outgoing president, according to People magazine.

One friend said Obama's opinion of Trump since inauguration "hasn't gotten any better."

Another source said Obama is "deeply concerned with what he's seen."

"But he's also optimistic and heartened that citizens aren't just watching it happen but engaging with neighbors and elected representatives at town halls," the source told People.

Former first lady Michelle Obama also reportedly joked about wearing all black in response to Trump's election.

"I'm going all black for the next couple of years," she joked.
