His younger brother Ron also became a comedian, received Leo's initial blessing, and started his career as Leo's impersonator. In 2000, the latter sued Ron for trademark violations and false advertising and won the case. Ron was therefore barred from using his brother's routines.Leo Gallagher became increasingly controversial in recent years, stereotyping Mexicans and making racist and homophobic jokes.
