Nicolle Wallace's new program, "Deadline: White House," makes its MSNBC debut on Tuesday afternoon at 4:00 p.m. ET
Wallace, who served as communications director under former President George W. Bush, is a frequently seen analyst on MSNBC's "Morning Joe" and NBC's "Today."
Political analyst Steve Kornacki had hosted the 4 p.m. slot on MSNBC since 2016, leading up to the presidential election. The network says Kornacki, who was promoted to national political correspondent for NBC News and MSNBC, will continue to contribute to the revamped show.
