President Joe Biden has canceled a planned speech in Philadelphia at the annual conference of the National Education Association after the union’s staff announced a strike. It set up picket lines Friday around the Pennsylvania Convention Center in downtown Philadelphia. Biden had planned to speak Sunday, but his campaign says the president is a “fierce supporter of unions and he won’t cross a picket line.” Biden still plans to travel to Pennsylvania over the weekend. The NEA has school employee union affiliates in every state. It has endorsed Biden.
