As he looks past the GOP primary and towards a likely general election rematch against President Joe Biden, Donald Trump will meet with members of the Teamsters Union in Washington Wednesday afternoon as he tries to cut into Biden’s support.

The former president will participate in a roundtable with the group’s executive board, its president and rank-and-file members as he targets the blue-collar workers who fueled his 2016 victory and who are expected to play a major role in November, particularly in critical Midwestern swing states like Wisconsin and Michigan.

Union voters tend to vote Democratic, with 56% of members and households backing Biden in 2020, according to AP VoteCast. And Biden has already received significant organized labor backing with early endorsements from the AFL-CIO and others. Trump is hoping to cut into that support as he casts himself as pro-worker and tries to exacerbate longstanding divisions between union leaders and rank-and-file members.
