According to two people familiar with the negotiations, Jen Psaki, the White House press secretary, is in advanced talks with MSNBC to join the network after she leaves the Biden administration.

One of the people said that Ms. Psaki could leave the White House next month.

While the details of her role are still being discussed, the negotiations have centered on an arrangement in which she could host shows both for MSNBC and for Peacock, the streaming platform of MSNBC's parent, NBCUniversal. The people said that Ms. Psaki could make regular appearances on MSNBC and NBC News.

The two people said that Ms. Psaki is only talking with NBCUniversal officials. One of them said that CNN was trying to bring Ms. Psaki aboard.

The news of Ms. Psaki's discussions with NBC was reported earlier.

The White House didn't have anything to say about Jen's length of planned service or future plans. Jen is here and working hard every day to get you the answers to the questions that you have, and that's where her focus is.

The president's first press secretary was Ms. Psaki. She was the chief spokeswoman for John Kerry when he was the secretary of state.

The daily White House briefing, a tradition that mostly fell by the wayside in the Trump years, was revived by Ms. Psaki and has won praise for her handling of reporters.

Her exchanges with the Fox News correspondent are often shared on social media platforms. The phrase "Psaki Bomb" is used by liberals who enjoy seeing her rebukes.

The former spokeswoman for Harris was hired by NBC to host a show.

Michael D. Shear was involved in the reporting.
