President Trump early Tuesday said he will appear on "Fox & Friends" on a weekly basis through Election Day, but co-host Steve Doocy said Fox News has yet to decide whether that will happen.

"We've agreed to do it once a week in the morning," Trump said in the early stages of a phone interview with "Fox & Friends." Trump said he would call in "mostly on Monday, and if we have to, Tuesday," adding it would be "like the old days."

At the end of the interview Trump said he plans to come on the show every week, prompting a response from Doocy.

"Mr. President, thank you very much. You may want to do it every week, but Fox has not committed to that," Doocy said. "We're going to take it on a case-by-case basis. And Joe Biden, as well, is always welcome to join us for 47 minutes, like we just did with the president."

Trump did not respond to Doocy's comment.

President Trump, an avid viewer of Fox News, was a regular guest for years before announcing his candidacy in 2015.

Fox most notably gave Trump his own weekly segment called "Monday Mornings with Trump" in 2011, The Hill reported. 

During Tuesday's show, Doocy noted Biden, Trump's Democratic challenger, has declined numerous interviews with the program. He also has turned down other Fox News invitations though chief political anchor Bret Baier told his 1.4 million Twitter followers they “keep trying” to lure the former vice president on air. 

Biden has conducted prior interviews with ABC News, CNBC, CNN and other prominent media outlets.
