President Donald Trump took to Twitter Saturday to reveal he had learned former President Barack Obama wiretapped phones at Trump Tower before the election. Trump didn't offer any evidence, but that doesn't mean his claims aren't backed by supporters.
As you can imagine, Trump's accusations set-off a flurry of stories from news outlets. The New York Times reports it all began with radio talk show host, Mark Levin, who said on his Mar. 2 broadcast Obama had used the “instrumentalities of the federal government” to wiretap Trump and called it "the big scandal."
Breitbart News followed up with an article, the following day -- Friday -- outlining Levin's claim. The Breitbart article pieced together a timeline and apparent evidence supporting Trump's claims.
Then, on Saturday Trump fired off about the allegations in a series of tweets.
The New York Times reported on Sunday that F.B.I. director James Comey asked the Department of Justice to reject Trump's wiretapping allegations.
On Monday, when counselor Kellyanne Conway was asked on "Fox & Friends" about the claims she said as President, Trump "has information and intelligence that the rest of us do not." Conway cited "credible news sources" when asked what sparked Trump's claims.
