Florida Sen. Marco Rubio’s Twitter comment Jan. 27 referring to an unnamed “national teachers’ union” not wanting to return to work until 2022 did not go unnoticed by AFT President Randi Weingarten.

Weingarten’s full response reads as follows: “Marco Rubio is lying. Our union has been talking about reopening since April, in fact I published an OpEd on it this week. The fact reopening safely costs money. Trying to withhold money from schools only slows down reopening. Stop lying Senator.”
