Roger Clinton, 59, was arrested for DUI on Sunday night in Redondo Beach, California
He remains in jail where his bail is set at $15,000, and is set to appear in court in Torrance on Monday afternoon
Roger is the half-brother of President Bill Clinton and brother-in-law of Hillary
The arrest comes just two days before the California primary, which Hillary hopes will make her the presumptive Democratic nominee
Roger was arrested for DUI in 2001 as well, and served a year in prison in 1985 on a cocaine conviction after selling drugs to an undercover cop
The Secret Service gave Roger the code name 'Headache' while his brother was in office
