Former U.S. Attorney Tom Marino (R) is seriously considering challenging Rep. Chris Carney (D-Pa.), and is meeting with the National Republican Congressional Committee today in Washington, D.C., according to two GOP sources familiar with the meeting.

Republicans believe that Carney is vulnerable in his predominantly conservative northeastern Pennsylvania district, which has consistently voted for GOP presidential candidates.

GOP party leaders attempted to recruit Marino to run in the 2008 cycle against Carney, but he eventually declined. According to one Republican operative familiar with the situation, Marino requested today’s meeting with NRCC and he is still in the early stages of any potential campaign.

The GOP operative stressed that the committee is in the process of meeting with several candidates.

State Rep. Mike Peifer (R) also is considering a bid and has met with the committee.
