State Assemblywoman Kimberly Jean-Pierre, a 36-year-old Suffolk County Democrat, has tested positive for the coronavirus, becoming the third Albany lawmaker to contract the illness.

Jean-Pierre was tested Wednesday after one of her relatives fell ill, said Assembly Speaker Carl Heastie in a statement, which reported the lawmaker is now quarantined at home and “doing well.”

Jean-Pierre was in Albany on Wednesday and cast a vote from the floor of the Assembly. But she did not have contact with fellow lawmakers or her staff, Heastie said.

“I have ordered a deep cleaning of her offices in addition to the regular cleaning of the Assembly chamber and any other areas she may have visited in order to ensure the safety of everyone,” Heastie said.

Jean-Pierre’s office did not immediately respond to a request for comment.

A Senate spokesman said no senators have tested positive for COVID-19.

Last weekend, sexagenarian Brooklyn pols Charles Barron and Helene Weinstein both tested positive for novel coronavirus, which Heastie said Wednesday led to a perception that the electeds got special treatment because they had access to the hard-to-come-by tests.

Heastie batted away the allegation, saying that Assembly members and their staffs are being treated “the same way the general public is.”

Health experts have said at this point in the pandemic, elderly and people with chronic illnesses like diabetes, heart disease and lung disease should get priority for COVID-19 tests.

Heastie declined to say if other members or staff have been tested in recent days — and added he hasn’t been tested himself because he stays in shape and has been symptom-free.

“I feel like I’m in extremely good health, I’ve lost probably over 20 pounds over the past several months,” Heastie said Wednesday. “I would rather that test goes to somebody who really needs it.”

Other New York pols who have tested positive for the virus include Bronx Councilman Ritchie Torres, a 32-year-old Democrat.
