MSNBC's "PoliticsNation" celebrated the show's one-year anniversary (as well as its best ratings week ever last week!) last night at NYC's Hudson Terrace. Many guests turned out to toast Rev. Sharpton and the show's team, including MSNBC President Phil Griffin (pictured here with Rev. Sharpton), as well as many of MSNBC's hosts including Tamron Hall, Martin Bashir, Alex Wagner, Toure, Krystal Ball and Craig Melvin. Congressman Charlie Rangel (D-NY), former New York City Mayor David Dinkins and The Grio's Joy Reid were also in attendance.
