President Donald Trump joined Fox News on Sunday morning for a more than 45-minute interview, the first since Election Day 

He accused his FBI and Justice Department of potentially being involved in 'rigging' the election for Joe Biden

'The FBI and Department of Justice, I don't know, maybe they're involved – but how people are allowed to get away from this with this stuff is unbelievable'

Trump also claimed, without evidence, that even Democrats think he won

Said there's 'no way' Joe Biden earned more votes than Barack Obama

Trump called into the show from Camp David, where he spent the weekend 

He has barely spoken publicly since the election, but has been vocal on Twitter, where he claims he is the true winner and refuses to concede to Biden
