The anti-Portman ad ominously asks, "Who would sign up to speak for a (Haitian) dictator? Rob Portman."

Portman worked for a lobbying firm that required its attorneys to register as foreign agents in case they were assigned to work for overseas clients.

One of the firm’s clients was the Republic of Haiti, which was under the power of dictator "Baby Doc" until 1986. Portman was with the firm from October 1984 to October 1986. He did register as a foreign agent for the Republic of Haiti in 1985, and four other foreign-based clients.

But the only work Portman performed directly for a foreign account was on behalf of Hong Kong-based Duty Free Shoppers, Ltd., according to a sworn statement by a managing partner of Patton Boggs LLP in April 2005.

We rate this ad Mostly False.
