As is his habit on early Sunday morning, President Donald Trump was on Twitter attacking his enemies -- this time former Secretary of State Hillary Clinton.

A day after he attacked former President Barack Obama and Republican senators who are not falling in line with the GOP's proposed Trumpcare plan, Trump was back tweeting about the 2016 election

"Hillary Clinton colluded with the Democratic Party in order to beat Crazy Bernie Sanders. Is she allowed to so collude? Unfair to Bernie!" he tweeted -- although it is unclear why.

The president then promoted his appearance on Fox & Friends -- which has become the go-to safe space for Trump Administration officials.
