Fat Joe, Wyclef Jean, Jelly Roll Demand Prez Biden Act On Healthcare Transparency

Fat Joe, Wyclef Jean and Jelly Roll used their combined musical talents to spread more awareness for their Power to the Patients healthcare advocacy ... by bringing the message right to Congress' doorstep.

The artists performed last night at Hamilton Live in D.C. for about 500 Congressional and government officials, and TMZ Hip Hop got video from inside the show.

The trio's message was clear -- they're all calling for President Joe Biden to act immediately!!!

Wyclef corralled members of Congress onto the stage and passed them the mic while having them chant to Biden, "Power to the Patients" much to the amusement of Joe in the back ... pretty funny stuff.

Jelly Roll is coming off his Best New Artist win at the CMTs, but flexed his hip hop roots performing Eminem's "Lose Yourself" ... a motto he's applied to his career given his recent success.

Sources at the event tell us Joe, Clef and Jelly all met backstage and shared their fondness for each other's careers -- we hear Joe in particular is a huge fan of JR's "Need A Favor" hit from last year.
