Mayor Bill de Blasio says the NYPD and FBI are assessing information related to a potential al-Qaeda attack on U.S. soil on Monday, which they say is not yet considered credible and lacks specifics. NY1's Courtney Gross filed the following report.

It was a calm but cautious tone from Mayor Bill de Blasio after word came there was a possible terror threat on the eve of the presidential election.

"We are in a state of vigilance," de Blasio said.

The threat reportedly includes New York, Texas and Virginia.

De Blasio was notified of it several days ago. He called it nonspecific. 

"At this moment, we are still developing information on," de Blasio said. "The level of credibility is not clear. It is definitely not an overly specific threat."

"Obviously, we are in total coordination and consultation with the federal authorities, and we are already on a state of high alert for election day," said Governor Andrew Cuomo.

Nonetheless, the NYPD is being extra vigilant. New Yorkers should expect to see a larger police presence at the city's marathon on Sunday, throughout the city on Monday and at the polls on Tuesday. 

Police are also preparing for both Hillary Clinton and Donald Trump's election night parties, which are being held just blocks part in Manhattan. 

"It's going to be harder to get around certain parts of Manhattan, and there is going to be a very, very extensive police presence," de Blasio said.

The other question is, will New Yorkers just have to deal with a disorganized day, courtesy of the Board of Elections Take 2012, which saw some long lines and other problems at the polls. So is the mayor confident they can pull it off?

"In terms of the broad integrity of the voting process, yes. In terms of efficiency, that remains to be seen."

"This is the Super Bowl. It will be well-attended. And we have made all the preparations that we can make under the circumstances to make sure this election gets done well," said Michael Ryan, executive director of the Board of Elections.

Earlier this year, the mayor had offered the Board of Elections millions of dollars in funding to reform some of its processes. The board never took him up on his offer. 

"If they once again have these kinds of problems, I think the pressure will mount for bigger reform," de Blasio said.
