President Trump’s 2020 reelection campaign will no longer issue credentials to Bloomberg News because of its decision to investigate Trump, but not his political opponents, campaign manager Brad Parscale announced Monday.

Bloomberg News announced last week that it wouldn’t investigate its namesake owner, Mike Bloomberg, while he runs for president, or any other Democratic presidential candidate for that matter, but would continue to investigate President Trump.

“The decision by Bloomberg News to formalize preferential reporting policies is troubling and wrong,” Parscale wrote in a statement. "Bloomberg News has declared that they won’t investigate their boss or his Democrat competitors, many of whom are current holders of high office, but will continue critical reporting on President Trump.”

Parscale said he is “accustomed to unfair reporting practices” but Bloomberg News’ decision takes it too far because “most news organizations don’t announce their biases so publicly.”

Bloomberg launched his 2020 campaign last week with a one-minute ad, which was posted on social media. Along with the video, Bloomberg posted a written statement on his campaign website in which he laid out why he was the best candidate to defeat President Trump next November.

“Since they have declared their bias openly, the Trump campaign will no longer credential representatives of Bloomberg News for rallies or other campaign events,” Parscale wrote. “We will determine whether to engage with individual reporters or answer inquiries from Bloomberg News on a case-by-case basis. This will remain the policy of the Trump campaign until Bloomberg News publicly rescinds its decision.”

Republican National Committee chairwoman Ronna McDaniel said the GOP agrees with the decision.

“Media outlets should be independent and fair, and this decision proves that Bloomberg News is neither. The @GOP stands with @TeamTrump and will no longer credential Bloomberg representatives,” McDaniel tweeted.

"The accusation of bias couldn't be further from the truth. We have covered Donald Trump fairly and in an unbiased way since he became a candidate in 2015 and will continue to do so despite the restrictions imposed by the Trump campaign," Bloomberg Editor-in-Chief John Micklethwait told Fox News.

Micklethwait is the same editor who sent a memo to staffers, obtained by The Washington Post, in which he declared the newsroom will “continue our tradition of not investigating Mike (and his family and foundation)” and that it would extend the same policy to his opponents in the Democratic primaries, but not to President Trump.

Micklethwait added that “if other credible journalistic institutions” publish investigative work regarding the former New York City mayor, Bloomberg News will either publish or summarize it for readers. The decision to avoid investigating 2020 Democratic presidential candidates sparked backlash and confusion, including former Bloomberg Washington D.C. bureau chief Megan Murphy, who slammed the organization in a series of tweets.

“It is truly staggering that *any* editor would put their name on a memo that bars an army of unbelievably talented reporters and editors from covering massive, crucial aspects of one of the defining elections of our time. Staggering,” Murphy wrote. “This is not journalism.”
