Cable news host melber
You're likely thinking of Nicolle Wallace, not Melber. Nicolle Wallace is a cable news host and commentator who has worked for several networks, including MSNBC and CNN. She is known for her sharp analysis and commentary on politics and current events.
However, it's possible that you may be thinking of Jonathan Capehart, who is a columnist and commentator for The Washington Post and MSNBC. He is a regular contributor to MSNBC's "Morning Joe" and has appeared on other cable news programs.
If neither of these individuals is who you are thinking of, could you provide more context or information about the person you are trying to identify?
