Multiple members of Gov. Phil Murphy’s inner circle have said under oath in recent weeks they do not know who hired an official accused of rape for a top state job last year.

And Murphy on Tuesday wouldn’t say who did, turning back reporters' questions for the second time in less than a week.

Now, unhappy with those answers, a top lawmaker heading a special legislative investigation into Katie Brennan’s allegations, told NJ Advance Media she may call more witnesses to find out.

State Senate Majority Leader Loretta Weinberg, the co-chairwoman of the special legislative committee examining the matter, said she’s perplexed how three top officials for the governor haven’t been able to tell lawmakers who gave Brennan’s accused rapist, Albert J. Alvarez, a $170,000-a year job with the New Jersey Schools Development Authority.

“How could we be satisfied? We talked to three top people and nobody knows how he got hired,” Weinberg, D-Bergen, said.

Weinberg referred to Peter Cammarano, Murphy’s former chief of staff; Matt Platkin, the governor’s chief counsel; and Jose Lozano, who headed Murphy’s transition team. In recent weeks, all three men testified before the joint committee and all three said they didn’t know who hired Alvarez.

“If the governor would like to clear this up it would be helpful,” Weinberg said. “And if not, we might have to ask his closest advisers to see how somebody gets hired into a top position.”

Weinberg said the committee will call Lynn Haynes, Murphy’s deputy chief of staff for cabinet affairs whose signature was on a form Weinberg said told Alvarez he would get a job in the administration. But she didn’t say who else the committee may consider asking to testify.

Murphy’s spokesman, Dan Bryan, referred an inquiry into who hired Alvarez to Chris Porrino, the governor’s outside counsel. Porrino declined to comment.

Murphy so far refused to say who in his administration gave him the job.

“I’ve said everything I’m gonna say,” Murphy said at a public event in Newark Tuesday after he was asked the question by a reporter.

He punted on the same question on Friday.

Brennan has said Alvarez sexually assaulted her in her apartment in Jersey City in April 2017. He had driven her home from a campaign-related social gathering and asked to use the bathroom, Brennan has said. The Hudson County Prosecutor’s Office declined to file charges against him.

Alvarez was chief of staff to the New Jersey Schools Development Authority until he resigned Oct. 2 after he was contacted by the Wall Street Journal, which was preparing to publish a story about Brennan’s allegation and the administration’s failure to investigate or hold Alvarez accountable.

Murphy campaign and administration officials testified that Alvarez was told twice to look for a new job. But none have said they actually hired him.

Alvarez has denied he raped Brennan and has declined to comment on the hearings.

The legislative committee will hold its sixth public hearing Friday.
