O'Rourke is hoping to unseat Republican Ted Cruz in the fall.

Willie Nelson always has plenty of special guests at his annual 4th of July picnic outside Austin, TX. But this year, one of the invitees was looking to do more than just jam with the country icon. Enter Democratic Texas congressman Beto O'Rourke, who is in a fierce battle to unseat Republican Ted Cruz in a bid to flip the failed presidential candidate's U.S. Senate seat in this fall's mid-term election. 

O'Rourke, 45, who played bass in the band Foss with future At the Drive-In/Mars Volta singer Cedric Bixler-Zavala in the early 1990s, grabbed an acoustic guitar and a mic beside Nelson at the show on Wednesday (July 4) to jam on a pair of the host's iconic weed anthems, "Roll Me Up and Smoke Me When I Die" and "It's All Going to Pot," as well as the traditional tune "Will the Circle Be Unbroken."

The charismatic politician taking on the Senator, recently dubbed "blobfish" by late night host Jimmy Kimmel, was joined on stage by Margo Price and members of Asleep at the Wheel and The Head and the Heart during Nelson's festival-closing set.

In addition to their musical affiliation, both Nelson and O'Rourke are in favor of legalizing marijuana and have spoken out strongly against the Trump administration's family separation policies along the U.S.-Mexico border.
