Manhattan District Attorney Cyrus Vance is running unopposed in this election year, but he's trying to stay visible, giving NY1 an exclusive first look at a new public service announcement opposing federal legislation that would allow more guns to be legally carried on city streets.

But Wednesday morning, WNYC aired a report about Vance's decision not to prosecute a criminal case against two of President Trump's children in connection with a real estate deal. Vance had plenty to say about that story as well. Zack Fink has the exclusive story.

The real estate deal in question involves the Trump SoHo, a hotel and condominium project. Investors claimed that Trump's children repeatedly misrepresented how many units had been sold. That led to a criminal probe by the Manhattan DA's Office in 2010.

But it was dropped without any charges being filed after a lawyer for Trump, Mark Kasowitz, met with Vance in 2012. Kasowitz had contributed nearly $57,000 to Vance's campaigns.

Some of the money was returned before the 2012 meeting, but in the wake of the report by WNYC and the New Yorker, the rest of the donations have been returned. In his first public remarks since the story broke, Vance spoke to NY1 about whether he was influenced by the contributions.

"There has been no time in eight years where anyone's contributions to my campaigns made any difference in my decision-making on a case. I've made our decisions on the merits," Vance said.

Before this story broke, Vance had reached out to us to discuss a new public service announcement that his re-election campaign will be running that takes on the Concealed Carry Reciprocity Act. The federal legislation would allow gun owners from other states to carry their weapons in New York City, something they are currently barred from doing under local law.

Vance is now appealing to Trump to veto this legislation if it reaches his desk.

"Donald Trump understands as president — but as a New Yorker — that a safe city, and a city that is prosperous, is based upon the public feeling safe and being safe," Vance said.

Concerns over guns have been heightened in light of the Las Vegas shooting that claimed dozens of lives and injured several hundred more.

Vance had no primary opponent and he is running unopposed in the general election. The PSA is expected to be seen on platforms such as Facebook and Spotify.
