Republican Westchester County Executive Rob Astorino on Monday created a campaign committee for governor as he considers a challenge to Democratic Gov. Andrew Cuomo, said spokeswoman Jessica Proud. Astorino continues to weigh running as he takes this step of creating an exploratory committee. Former state GOP executive director Michael Lawler will manage the committee, which allows him to spend money as he travels the state to see if there is support for a bid. Astorino has said he will make a final decision on the race in about a month.
