I was just digging on McCarthy a couple days ago. Vortex Construction is owned by McCarthy's brother-in-law Bill Wages and McCarthy's wife was also listed at the time.

"Kevin McCarthy’s brother-in-law, Bill Wages, issued a statement "Monday afternoon following a Los Angeles Times story stating that Wages received no-bid government contracts worth more than $7 million through a program allowing Wages to claim Native American heritage."
