Bloomberg News claimed Sunday that Breitbart News and conservative radio host Mark Levin had not cited “independent” evidence to back up the claim that the Obama administration had conducted surveillance on Donald Trump’s aides in the 2016 campaign.

The story, which claimed the moves were aimed at undermining Trump’s candidacy, referenced commentary by radio host Mark Levin that made similar claims. … Neither Breitbart News nor Levin cited independent reporting to back up the assertions.

However, Levin cited several independent news sources in his Mar. 2 broadcast. Several of these, plus others, were also cited by Breitbart, including:
