Gov. Cuomo has loudly demanded more transparency at the MTA, but his handpicked enforcer on the agency’s board blew off filing his financial-disclosure form.

Larry Schwartz failed to meet the May 15 deadline revealing his outside employment, income and holdings — the only one of 19 board members to ignore the legally mandated submission. He was grilled on the matter by The Post amid calls from a watchdog demanding he comply.

On Saturday he finally got around to sending it in.

“It was an oversight, and it’s been fixed,” his spokesman told The Post.

But the delay spurred questions of whether he had something to hide.

“Schwartz seems unable or unwilling to file complete and timely state ethics disclosure forms,” said John Kaehny, executive director of Reinvent Albany, a reform group. “Other MTA board members follow the law, why can’t he?”

Schwartz, Cuomo’s former chief of staff, had been in violation for a month of state law requiring a full account of his finances, which can identify potential conflicts of interest. The governor appointed him to the MTA board in 2015.

Schwartz is known for aggressively championing Cuomo’s agenda, most recently by pressing the agency to hire a former prosecutor to examine overtime abuses.

This is not the first time he has failed to file his disclosure report. The Post reported in 2017 that Schwartz’s submissions to JCOPE had lapsed for two years. At the time, he claimed that, too, was an “oversight.”

The form Schwartz filed in 2018, which covers the previous year, says he had no outside employment. But Schwartz is the chief strategy officer at OTG, an airport concessions company, according to his bio on the MTA web site.

Meanwhile, Haeda Mihaltses, whom Cuomo appointed to the board in March and who works as vice president of public affairs for the Mets, listed no income for that job on her form.
