Gov. Kathy Hochul and New York City Mayor Bill de Blasio on Friday stressed cooperation between the city and state for strengthening security ahead of the 20th anniversary of the Sept. 11 attacks. 

Officials emerged from a security briefing on Friday afternoon with federal law enforcement to announce no credible threats have been made against New York City. Nevertheless, an enhanced security presence will be set up ahead of what's planned to be a day of events commemorating the anniversary of the attacks. 

Both Hochul and de Blasio sought to highlight their efforts to cooperate with each other, a public relationship they have sought to stress following the departure of former Gov. Andrew Cuomo, who had a famously combative relationship with de Blasio. 

"I thank you for the leadership you continue to show, the partnership, the hand you've reached out to me since the infancy of my administration," Hochul told de Blasio. "I know there's so much more we can do together." 

Cuomo and de Blasio during most of the pandemic were publicly at odds with each other on strategies to prevent further spread of the virus, including whether to close schools in New York. Hochul replaced Cuomo last month after he resigned in the wake of a sexual harassment scandal. 

By contrast, Hochul and de Blasio have stressed their efforts to work together. Hochul has also brought in other former rivals of Cuomo, including Sen. Mike Gianaris, the second-ranking Democrat in the state Senate. 

Still, de Blasio, who leaves office at the end of the year, is reportedly considering a run for governor himself in 2022, and Hochul has said she plans to run for a full term next year.
