New York (CNN Business)President Donald Trump, facing an ever-deepening scandal that threatens to swallow his presidency, appears to have lost a key ally in conservative media: The Drudge Report.

The narrative-setting news aggregation website, founded in 1995 by Matt Drudge, has spotlighted an overwhelming amount of negative news for the Trump White House in the last several weeks. It's marked a major shift from how the outlet had previously covered the President.

"He's reacting to changing circumstances," a person close to the media mogul, who said Drudge had grown exasperated with Trump, told CNN Business.

This should worry Trump as he faces an impeachment inquiry in the House of Representatives for pushing Ukraine to investigate former Vice President Joe Biden, the leading Democratic presidential contender, and Biden's son Hunter.

"He's one of the dominoes that would have to fall for the right-wing media to allow Trump to be removed from office," said John Ziegler, a conservative who was an occasional guest host on Drudge's old radio show and writes columns on media for Mediaite.
