Teamsters president seeks speaking slot at both party conventions

• "We have made it clear we want our members' voices heard at both conventions," Deniz said, adding that it's an unprecedented ask from the union. "Sean is a leader who wants to make sure our members' voices are heard."
• The New York Times reported on O'Brien's request earlier Monday.

The big picture: O'Brien has invited several presidential candidates to speak before the Teamsters and has indicated he is delaying an endorsement decision until later in the year, per the Times.

• The Republican National Convention is in July, followed by the Democratic National Convention in August.

State of play: Biden has described himself as the "most pro-union president ever" and last year became the first sitting U.S. president to visit a picket line.

• The United Auto Workers and the Laborers' International Union of North America have both already endorsed Biden's re-election bid.
• While the Teamsters still overwhelmingly gives to Democrats, in February it made its first major donation to the RNC since 2004. O'Brien also personally met with Trump in January.

• The International Brotherhood of Teamsters has approximately 1.3 million members.

Our thought bubble, from Axios' Nathan Bomey: Although the leadership of unions like the Teamsters and the UAW have historically been progressive, many of their members are conservative.

• Case in point: The UAW has endorsed Biden for reelection but has acknowledged that about a third of its members voted for Donald Trump in 2016 and 2020.
