The Republican Party and Trump oppose a recount. They’ve warned that the case threatens Pennsylvania’s ability to certify its election results before the Dec. 13 federal deadline.

Green Party presidential candidate Jill Stein has spearheaded recount efforts in Pennsylvania, Michigan and Wisconsin. Trump narrowly defeated Democrat Hillary Clinton in all three states.

Stein’s team hasn’t produced evidence of hacking but has called Pennsylvania’s election system “a national disgrace.”
