President Joe Biden marked a belated labor day at the White House Wednesday by speaking about how intimately he knew unions. 'By the way, of course, I sleep with a NEA member every night,' Biden told a crowd gathered in the East Room. 'Same one. same one,' he added as attendees applauded. As a teacher, first lady Jill Biden belongs to the National Education Association labor union. 'Jill had her first day of full time teaching yesterday - this year, back to school,' Biden also added.
