Former MTA chairman Joe Lhota says he plans to file papers this week to run for mayor.
Lhota made the comment to reporters Monday after speaking to the New York Building Congress.
NBC 4 New York first reported Lhota planned to leave the MTA and vie for the top city job.
In his speech, Lhota noted that he left the MTA last month. He said he wouldn't have done that if he didn't plan to run.
The Republican was a deputy mayor and budget director under Rudy Giuliani. He later went into business before taking the MTA post in 2011.
The field for November's election already includes several other declared and likely candidates.
