President Biden’s staff asked the American Federation of Teachers union for advice on how to reopen COVID-affected schools before the commander-in-chief even took office, union president Randi Weingarten told lawmakers Wednesday.

“We were talking to the Biden transition team before he was sworn into office,” the 65-year-old testified to the Select Subcommittee on the Coronavirus Pandemic.

“Did they reach out to you?” asked subcommittee chairman Brad Wenstrup (R-Ohio).

“The Biden transition team reached out to us,” Weingarten said.

“Did that include the next CDC director or anybody that went to work for CDC?” Wenstrup followed up.

“I don’t want to speculate,” hedged Weingarten, who added that the union’s first conference call with the agency took place on Jan. 29, 2021.

The Post revealed Tuesday that the AFT and the National Education Association were in touch with both White House officials and CDC Director Rochelle Walensky right up to the Feb. 12, 2021 issuance of guidance that slowed students’ return to in-person instruction.

According to records obtained by the conservative watchdog Americans for Public Trust, Weingarten spoke with Walensky by phone on Feb. 7 and Feb. 11, with a CDC official following up with her and NEA chief Becky Pringle following the latter conversation.

Both unions also asked for help from the White House and CDC in crafting a national press strategy, the records show.

Earlier documents obtained in May 2021 through Freedom of Information Act requests found that AFT suggested language for two provisions that later made it into the administration’s school-reopening guidance.

One provision carved out work-from-home allowances for educators who were deemed to be at “high risk” for COVID-19 or had “household members” at greater risk of infection.

A second provision included the option for schools in communities with high levels of viral transmission to return to in-person learning.

Weingarten and her attorney have acknowledged that AFT suggested the two proposals, but maintained they were appropriate and within the union’s authority.

“What happened was there was one particular edit that they accepted,” Weingarten said Wednesday. “There were several ideas we proposed.”

At the time, however, a union official even went so far to refer to AFT as the CDC’s “thought partner” and expressed gratitude to the agency for its “openness to the suggestions made by our president, Randi Weingarten.”

This is a developing story.
