Biden scoffs at Trump's attacks

MORE aimed at him earlier in the day.

"I understand the president has been tweeting about me this morning," Biden said at a campaign event in Iowa, followed by a laugh. "I wonder why the hell he’s doing that."


Trump in an early morning Twitter spree retweeted nearly 60 posts, most of which knocked Biden and his 2020 presidential campaign.

Trump "welcomed" Biden to the campaign trail last week, calling him "Sleepy Joe" in a post on Twitter.

Trump has reportedly rebuffed advice to ignore Biden from his political advisers, who worry the president risks elevating the former vice president's profile, according to CNN.

Biden has shown a penchant for firing back at Trump, saying in a tweet earlier this week that he is "sick of this president badmouthing unions."

Biden is leading the Democratic field in several early polls.
