Former Mayor Bill de Blasio is eyeing a run for Congress. 

The former mayor announced on Twitter Wednesday that he is forming an exploratory committee to run in a proposed open district created by a court-ordered special master who was tasked with redrawing the state’s congressional maps. The current district is held by longtime Rep. Jerrold Nadler, who has announced he will be running against Rep. Carolyn Maloney in the newly formed NY-12 district spanning the Upper West and Upper East Sides.

De Blasio previously eyed a congressional run under a different set of proposed maps released earlier this year, but decided against it in February.  

The former mayor had also considered a gubernatorial run. 

The newly drawn 10th district is heavily Democratic and includes neighborhoods below 14th street like the East Village and Tribeca in Manhattan to Brooklyn Heights, Borough Park and de Blasio’s own Park Slope neighborhood in Brooklyn.

Already, de Blasio has picked up support from an influential Democrat, Kings County Democrats boss Assemblywoman Rodneyse Bichotte Hermelyn.

"Bill de Blasio is the most qualified progressive candidate who I believe can win this diverse seat," the party executive committee chair said in a statement. 

In an interview with NY1, de Blasio said he’s taking the decision seriously, and highlighted his personal connection to the district.

“I am looking at this very seriously, very quickly, with passion,” de Blasio said. “There’s so much here that just to me is very personal. And I saw it, and I said, ‘This is a community I fundamentally believe I could serve well and passionately.’”

The courts have until Friday, May 20 to finalize the boundaries for the newly drawn maps, which would end the process that delayed the Congressional and state Senate primaries from June 28 to August 23.

Other candidates eyeing a race for the newly created district include state Sen. Brad Hoylman.
