As he continues to weigh a 2016 presidential bid, Maryland Gov. Martin O’Malley (D) has added two staffers in recent months to his political action committee, both with ties to the Center for American Progress, a liberal think tank in Washington.

Sarah Miller, who served on the policy team of Hillary Clinton’s 2008 presidential campaign, was hired as policy director for O’Malley’s Washington-based PAC, known as O’ Say Can You See, a spokeswoman for the PAC confirmed Wednesday.

Miller was also previously a close aide to John Podesta, a longtime Clinton adviser, at the Center for American Progress. Podesta is expected to play a leading role in a 2016 White House bid by Clinton. Miller’s hiring, which took place two months ago, was first noted Wednesday morning by MSNBC.

O’Malley’s PAC has also recently hired a second communications staffer. Megan Adams previously worked at the Center for American Progress as executive coordinator, a post that involved managing the executive team’s day-to-day operations. Adams has been on board with O’Malley’s PAC for ab out a month.

Adams joins communications consultant Lis Smith. She has worked with O’Malley for several years, including the first part of his tenure as chairman of the Democratic Governors Association in 2011.

Both Miller and Adams signed up with O’Malley prior to this month’s elections, in which O’Malley’s hand-picked candidate to succeed him in Maryland, Lt. Gov. Anthony G. Brown (D), unexpectedly lost to Republican Larry Hogan. The result has been viewed by some as a setback for O’Malley’s ambitions.

Before the mid-term elections, O’Malley told The Post that he probably will have decided whether to move forward with a presidential bid by the time his tenure as governor ends on Jan. 21.

Another Washington region Democrat, former Virginia senator Jim Webb, announced late Wednesday that he is launching an exploratory committee to consider running for the presidential nomination.
