Trump goes on Twitter rant accusing ex-President Obama of 'tapping phones' at Trump Tower prior to election

In a series of tweets issued early Saturday morning, Donald Trump accused ex-president Barack Obama of "tapping" the phones at Trump Tower just prior to the election while comparing the former president to Richard Nixon.

Following a tweet defending embattled Attorney General Jeff Sessions over his contacts with the Russians, Trump suddenly changed gears with a startling collection of tweets attacking Obama, although it is unclear what Trump is directly alluding to.

"Terrible! Just found out that Obama had my "wires tapped" in Trump Tower just before the victory. Nothing found. This is McCarthyism!" Trump wrote.

The tweets can be viewed below:

It is possible that Trump's allegations are the result of an article published at Breitbart, accusing Obama of instigating a "silent coup" against the sitting president.
