BOISE, Idaho (AP) — Idaho billionaire Frank VanderSloot says he'll support Republican Marco Rubio for president — another big donor endorsement for the Florida senator.

VanderSloot is the founder and chief executive of the health care products company Melaleuca. In the 2012 presidential race, he and his company gave $1.1 million to the super political action committee that backed the candidacy of Republican nominee Mitt Romney.

VanderSloot was one of Romney's national campaign finance co-chairs, raising at least $2 million for the campaign. VanderSloot is the latest major GOP donor to sign on with Rubio. Others include investor Paul Singer and hedge fund manager Cliff Asness.
