(Reuters) - The first day of Facebook Inc's effort to stop new political advertising being introduced in the final stretch of U.S. election campaigning was marked by complaints that the planned moratorium was beset by glitches.

Democratic presidential candidate Joe Biden's digital director Rob Flaherty slammed the social media giant on Tuesday, saying on Twitter its systems broke "within seconds of launching the silly, performative pre-election hoop-jumping exercise."
