Maryland Gov. Martin O’Malley (D) is scheduled to return to the national talk show circuit Sunday with an appearance on CNN’s “State of the Union.”

CNN is promoting the booking as “the second installment of our series of interviews with possible presidential party picks in 2016” and says it will be an “opportune moment” to get O’Malley’s take on a potential White House rival, New Jersey Gov. Chris Christie (R).

An O’Malley aide said he accepted the offer to appear with the hope of promoting his efforts to raise the minimum wage in Maryland and to urge Congress to act on an extension of emergency unemployment benefits, two measures aimed at expanding the middle class.

O’Malley is not going on the show to promote his presidential ambitions or engage on the Christie scandal over massive traffic jams on the George Washington Bridge, said the aide, who requested anonymity because he was not authorized to speak for the governor.

Talk of an O’Malley White House bid has been largely overshadowed in recent months by the speculation that Hillary Clinton will be the Democratic nominee in 2016.

O’Malley, who was a Sunday talk show regular in 2012, made far fewer appearances last year.

In its promotion, CNN says that while O’Malley doesn’t have the presence of Clinton or Vice President Biden, “some compare him to a little known governor from Arkansas with minimal political clout or electoral votes who won it all in 1992.”

The show airs at 9 a.m. and repeats at noon.
