U.S. President Donald Trump's re-election campaign said on Monday it will no longer issue press credentials to reporters working for Bloomberg News, accusing the agency owned by Democratic presidential hopeful Michael Bloomberg of "bias."

"As President Trump's campaign, we are accustomed to unfair reporting practices, but most news organizations don't announce their biases so publicly," Trump's campaign manager Brad Parscale said in a statement.

The news agency said following Bloomberg's announcement of his presidential bid that it would no longer critically cover the Democratic presidential candidates – including Bloomberg and his rivals – but would go on covering Trump.

What did Trump 2020 announce?

The Trump campaign will no longer credential representatives of Bloomberg News for rallies or other campaign events, and will decide "whether to engage with individual reporters or answer inquiries from Bloomberg News on a case-by-case basis," Parscale said.

It was not immediately clear whether the Trump White House would change how Bloomberg reporters are treated.

Bloomberg, former New York City mayor and billionaire media mogul who owns the eponymous news organization, announced on November 24 that he would seek the Democratic nomination for president.

Separately, he is spending 100 million U.S. dollars of his own money on digital ads attacking Trump.

How did Bloomberg News respond?

Bloomberg News quoted editor-in-chief John Micklethwait as saying "the accusation of bias couldn't be further from the truth" in response to the Trump campaign's claim of bias.

"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."

Does Bloomberg have a path to the White House?

After Bloomberg announced his White House candidacy, Micklethwait released a memo stating the news agency would "continue our tradition of not investigating Mike (and his family and foundation) and will extend the same policy to his rivals in the Democratic primaries."

However, he said, the business-focused news organization would continue "to investigate the Trump administration, the government of the day."

"There is no point in trying to claim that covering this presidential campaign will be easy," Micklethwait added.
