Some conservative fans expressed outrage at Nelson's endorsement of the candidate, with many saying they would boycott his music and concerts. "Beto embodies what is special about Texas, an energy and an integrity that is completely genuine". The report was posted to Nelson's Facebook page on Thursday.
From campaigning to legalize marijuana to supporting the LGBT movement, Nelson has scarcely hidden his progressive credentials during his long career. Maybe you're not as big a fan of his as you pretend to be if y'all ever thought Willie was a Republican.
"If thats (sic) true I'm done after 45 years." another fan commented.
O'Rourke told Colbert about his experience living in El Paso - the western Texas town that borders Mexico - and earned applause when he immediately and bluntly said, "We don't need a wall". "You'd have to be a fairly peripheral fan to be surprised by this".
Other fans said those complaining were ignorant of who they supported.
"I am grateful to everyone who has put their life on the line for this country, every member of law enforcement and every one of our first responders", O'Rourke said. Tickets are free, but attendees will need to RSVP at O'Rourke's website.
