Jeffries, a 52-year-old New Yorker, is running for House Democratic leader for the next two years.
If he is elected as expected during closed-door voting, he would become the first Black person to hold a top party leadership job in the House or Senate.
"Meaningful policymaking and public engagement opportunities should be robustly distributed regardless of length of service," Jeffries wrote in a letter to fellow Democrats.
Running for election as part of Jeffries' team are Representative Katherine Clark, 59, who is seeking the No.
2 Democratic whip job, and Pete Aguilar, 43, vying for Jeffries' current job of Democratic caucus chairman.
