"Greta is a true pro with a proven record of tough journalism," Griffin said. "Her broad range of experience and sharp news judgment will be of great value to MSNBC as we build on our momentum going into a new year and a new administration."
"I'm thrilled to start my next chapter at MSNBC," added Van Susteren. "The network is the right destination for the smart news and analysis I hope to deliver every day, and I look forward to joining the talented journalists and analysts I respect there."
According to the network, Van Susteren will be hosting a Washington, D.C.-based news program called For the Record With Greta, which will air weeknights from 6-7 p.m. ET beginning next Monday. The show will provide news coverage and analysis of the day's top headlines, "spanning politics and beyond."
"MSNBC is thrilled to welcome @greta," a message from MSNBC's official Twitter, accompanied with the official press release, read. "Don't miss #ForTheRecord beginning Monday, January 9."
Van Susteren also took to Facebook on Thursday, posting a lengthy message about her new role. "Get ready!" she teased. "You are about to join me on an adventure!"
The Appleton, Wisconsin, native confirmed her departure from Fox News via Facebook on Sept. 6, 2016, telling fans, "Fox has not felt home to me for years."
"Yes, I have left the Fox News Channel," Van Susteren, who had hosted On the Record since 2002, explained. "I made my decision and informed Fox News of my decision that I was leaving Fox News Channel per my contract."
