Presidential historian: Trump is 'irrational' and 'desperately trying to hold on to power'

04:50

Presidential historian Michael Beschloss tells Andrea Mitchell that right now "we've got an irrational president who's desperately trying to hold on to power. He's facing enormous legal and financial problems if he leaves the presidency. Even if it's irrational, he's going to try to do almost anything he can to hold onto the presidency even though we rational people know it's impossible."
