(CNN)President Donald Trump abruptly ended a solo interview with CBS News' "60 Minutes" Tuesday and did not return for an appearance he was supposed to tape with Vice President Mike Pence, according to multiple sources familiar with what happened.

After camera crews set up at the White House on Monday, Trump sat down with host Lesley Stahl for about 45 minutes on Tuesday before he abruptly ended the interview and told the network he believed they had enough material to use, according to two sources.

CBS News did not immediately respond to a CNN request for comment.

With about two weeks until the election, Trump has spent this week lobbing scatter-shot attacks and growing upset at depictions portraying his campaign as doomed. His truncated taping on "60 Minutes," which was followed by a cryptic tweet accusing Stahl of not wearing a mask at the White House, seemed an extension of what has been Trump's visible irritation as he enters the campaign's final days.

Former Vice President Joe Biden and California Sen. Kamala Harris were also interviewed by "60 Minutes" and all four are scheduled to appear in the same program on Sunday. While Biden and Harris taped their interviews separately, Trump and Pence were scheduled to appear on camera together, like they did four years ago, for a walk and talk session. But Trump did not return for the appearance with Pence, sources said.

The interview is slated to air this Sunday.

Facing a major national polling deficit against Biden, Trump has grown combative this week, lobbing accusations and insults as time runs out to win back voters.

On Monday he called Dr. Anthony Fauci a "disaster" and accused the news media of being "criminals" for not covering unfounded accusations against Biden.
