President Trump persuaded several Fox News hosts to leave the network and take up major roles in his administration.

Now a Trump is joining the network.

Lara Trump, Mr. Trump’s daughter-in-law and a former co-chair of the Republican Party, will begin hosting a new weekend show on Fox News on Feb. 22, the network is set to announce on Wednesday.

The president and his children are frequent guests on Fox News. But there is no precedent for the close relative of a sitting president to host a high-profile show on a major television news channel.

“My View with Lara Trump,” expected to air on Saturdays at 9 p.m. Eastern, will include a mix of analysis and interviews with influential figures. The network is describing the show as focused on “the return of common sense to all corners of American life,” echoing a phrase, “common sense,” that the Trump administration has frequently deployed.

Ms. Trump, 42, who is married to the president’s son Eric, is no stranger to a television studio. She worked for several years as a producer on “Inside Edition,” and served as an on-air contributor to Fox News from March 2021 to December 2022.

“Lara was a total professional and a natural when she was with us years ago,” Suzanne Scott, the chief executive of Fox News Media, told The New York Times in a message on Wednesday. “She is very talented and is a strong, effective communicator with great potential as a host.”
