WASHINGTON (AP) - A Washington watchdog group says two companies that gave money to a pro-Jeb Bush super political action committee are hiding the true sources of their money.

WASHINGTON (AP) A Washington watchdog group says two companies that gave money to a pro-Jeb Bush super political action committee are hiding the true sources of their money.

The group, Citizens for Responsibility and Ethics in Washington, has complained to federal regulators about what it calls illegal "straw donors."

The two limited-liability companies in question are TH Holdings and Heather Oaks. Each made a $100,000 contribution earlier this year to the super PAC Right to Rise.

Bush is one of many 2016 presidential candidates who are benefiting from super PACs, which do not have any contribution limits. The watchdog group highlights how those super PACS are not always as transparent as voters may think.

A spokesman for the super PAC says the donations were proper.
