Yes. I've seen screenshots of the founder of BRCC, Evan Hafer's political donations on fec.gov. Since it's easy to fake an image, I checked the FEC website for his name. He gave to Democrat Tulsi Gabbard in 2019. In 2018 he gave to a Republican running for Senate in Nevada. Both of those list BRCC as his employer. Person with the same name but occupation of Department of Defense in 2008, donated once to Obama for America but also donated four times to John McCain but listed employer as US Army. I have not seen confirmation that those donations are in fact the same person.
Gabbard is in the National Guard and may be why he donated to her campaign. Though I would never vote for her, she was the the least offensive of the Democrat nominee's. So yes, he donated to a Democrat for President this election cycle.
