Mamdani celebrates victory in 'reborn' New York City

While casting his vote for himself on Tuesday morning, independent candidate for mayor of New York City and former Gov. Andrew Cuomo said President Donald Trump does not support him but "opposes Zohran Mamdani."

"The president does not support me. The president opposes Zohran Mamdani," Cuomo said when asked if he accepts Trump's recent endorsement.

Cuomo was also asked what's at stake nationally in this election, to which he told reporters, "I think what you're seeing is a civil war in the Democratic Party that has been growing for a while."

The former governor said Trump believes Mamdani is an "existential threat" and that the "momentum is on our side."

Vice President JD Vance urged voters in New Jersey to cast their vote for Republican gubernatorial candidate Jack Ciattarelli, as the race tightens between Ciattarelli and the Democrats' pick, former Navy helicopter pilot Mikie Sherrill.

"Get out there and vote for Jack if you live in NJ. New Jersey is such a great state but it's suffered too long under crap leadership," Vance wrote on Tuesday.

According to a Quinnipiac poll, Ciattarelli is lagging Sherill only by single digits in the race, with Sherill leading Ciatttarelli by 8 points in the full ballot matchup.

Former President Barack Obama has previously endorsed Sherill, saying her "integrity, grit and commitment to service are what we need right now in our leaders."

In addition to being backed by Vance, Ciattarelli also boasts the support of President Donald Trump.
