Security, diversity visa lottery, vetting: The latest on the NYC attack

Investigators work around the wreckage of a Home Depot pickup truck, a day after it was used in an terror attack, in New York on November 1, 2017.
The pickup truck driver who plowed down a New York cycle path, killing eight people, in the city's worst attack since September 11, was associated with the Islamic State group but "radicalized domestically," the state's governor said Wednesday. The driver, identified as Uzbek national named Sayfullo Saipov was shot by police in the stomach at the end of the rampage, but he was expected to survive. / AFP PHOTO / Jewel SAMAD (Photo credit should read JEWEL SAMAD/AFP/Getty Images)

Authorities say the man responsible for Tuesday's deadly truck attack in Manhattan planned the attack for weeks, and left behind a note in his rental truck declaring his support for the Islamic State.

John Miller, deputy commissioner of the NYPD, said the letter, written in Arabic, stated that ISIS will "endure forever." Miller said investigators are still working to reconstruct the suspect's actions over the last few weeks as he prepared for the attack.

New York Gov. Andrew Cuomo described the incident as a "classic case of a radicalization of a domestic jihadist who associated with ISIS," telling CBS on Wednesday that "the best evidence we have is that he was a 'lone wolf.'"
