New York Republican Chairman Ed Cox on Friday knocked New York City Mayor Bill de Blasio’s impromptu trip to Germany to attend events related to the G20 summit.

Cox, in a statement, said de Blasio should simply turn over the job of being mayor.

“Bill de Blasio is so derelict in his job of Mayor, he should give it up and let someone else take over his responsibilities and duties, permitting him to return to his full-time roots as a protester and political rabble-rouser,” Cox said. “New Yorkers deserve so much better.”

De Blasio has sought to extend his national profile during his first term, taking several trips to burnish a leadership credential on the left.

The trip comes as de Blasio’s re-election bid for a second term is just getting underway. He likely Republican opponent is Assemblywoman Nicole Malliotakis, a Staten Island state lawmaker.
