Election Day for Bill de Blasio is well more than a year away, but the mayor has already amassed a healthy-sized campaign account. NY1's Josh Robin filed the following report.

Mayor Bill de Blasio kicked off the city’s summer youth job program, beginning somberly as he turned to Nice.

"There are no credible and specific threats against New York City at this time," de Blasio said.

An NYPD team will be studying Thursday's massacre for ways of preventing similar carnage here.

The mayor didn't take questions. If he did, a building a short walk away may have come up. A new probe from the city's Department of Investigation surrounding it finds a "complete lack of accountability within city government." It centers over how a change in deed restriction allowed an AIDS hospice center to be converted into condos.

Several law enforcement agences are also looking into the mayor's fundraising. He's denied wrongdoing.

The investigations have de Blasio's would-be rivals certainly looking to challenge him, but so far, there have been no major commitments.

Scott Stringer, the city's comptroller, is thought to be eyeing a primary. Campaign finance numbers released Friday show him with more than two-thirds of de Blasio's estimated balance - $1.45 million for Stringer, $1.67 million for the mayor.

One of de Blasio's top political aides apparently doesn't think Stringer is all that. John Del Cecato tweeted "what a powerhouse" atop Stringer's haul.

The gap widens greatly versus Republican City Councilman Eric Ulrich. The Queens lawmaker has $9,240, less than a percentage point of the mayor's nearly $1.7 million.

Numbers also are emerging from the mayor's nonprofits. The since-shut Campaign for One New York raised $60,000 this winter, and a national nonprofit raised $350,000, donations that are far higher than law allows to the mayor's traditional campaign chest.

Spending also shows tens of thousands of dollars spent on legal fees.

"Why all this money spent on legal and compliance issues when the purpose of the Campaign for One New York was about the mayor's agenda, and universal pre-k and affordable housing?" said Dick Dadey of Citizens Union.

A de Blasio campaign spokesman declined comment.
