Senate Majority PAC, a super PAC dedicated to electing Democrats to the Senate, announced Wednesday the hiring of two new staffers:

• Karyn Brockman will be the super PAC’s finance director. Most recently, she worked on now-Sen. Christopher S. Murphy’s, D-Conn., 2012 Senate campaign.
• Ty Matsdorf has signed on as campaigns and communications director. CQ Roll Call profiled Matsdorf as a Hill aide in 2009, when he was a communications director to Sen. Max Baucus, D-Mont. More recently, Matsdorf ran the war room for American Bridge 21st Century, a Democratic opposition research super PAC. He will continue with his other job at the newly formed Messina Group while working with Senate Majority PAC.
