The Daily Caller is promoting its youngest reporter, Alex Pfeiffer, to the highly scrutinized role of White House Correspondent.

Pfeiffer, 20, will replace current Daily Caller White House reporter Kaitlan Collins, who will join CNN as a White House reporter on Monday.

“Donald Trump once referred to Alex Pfeiffer as The Daily Caller’s ‘young apprentice reporter,'” editor-in-chief Vincent Coglianese said. “The apprentice has now become the master. Pfeiffer is an exceptionally curious and competent journalist. This is a big win for American news consumers.”

Since joining the right-leaning digital news outlet full-time less than two years ago, Pfeiffer has broken a number of notable political stories.

Most recently, he was the first to report that the man the FBI identified as the congressional baseball practice shooter, James Hodgkinson, had died of his injuries. He also first reported President Donald Trump’s plans to roll back some of President Barack Obama’s policies toward Cuba, which Trump will roll out later this week.

But Pfeiffer will have his work cut out for him.

After she caught heat from fellow White House reporters in February for failing to press Trump over revelations about contacts between his campaign and Russian officials, Collins distinguished herself as a tough questioner, regularly confronting White House press secretary Sean Spicer.

Though many news organizations reevaluated their political coverage following the 2016 election, the Daily Caller's coverage has largely remained unchanged, though it has increasingly attempted to highlight what it views as biased media coverage of the new administration.

In an email with Business Insider earlier this year, Coglianese said the Daily Caller would be covering more political media stories.

"We're covering the media a lot more now. The reflexive hysteria among the mainstream press has been deeply revealing and totally intriguing to document. We'll keep following it," Coglianese said.
