Washington ? Republican presidential candidate Sam Brownback, an outspoken critic of the violence in Sudan, divested his stock portfolio of companies that do business with the African nation.

Brownback listed sales of nearly two dozen investments, several of which were mutual funds whose holdings include companies active in Sudan, according to a financial disclosure report he filed Tuesday. Among them was a mutual fund in the name of Brownback’s wife valued between $50,000 and $100,000.

“Most of the movement of mutual funds in the portfolio was at the direction of the family to divest of Sudan-related investments,” Brownback spokesman Brian Hart said.

Brownback also listed a blind trust held jointly with his wife that is valued between $1 million and $5 million. Last year, Brownback aides said he would seek legal advice on whether he could request that any Sudan-related investments be sold, but under the rules of the trust Brownback cannot be made aware of any transactions.

Brownback was the first presidential candidate to make his financial report public Tuesday as he filed it with the Federal Election Commission.

Other candidates filed their reports with the FEC by Tuesday’s deadline. The FEC will make them public within days.

Sen. Hillary Rodham Clinton, D-N.Y., and Republican Tommy Thompson joined three other presidential candidates in obtaining extensions to file their personal financial disclosure reports.

The others who received 45-day extensions are Republicans: former Massachusetts Gov. Mitt Romney, Sen. John McCain of Arizona and former Virginia Gov. Jim Gilmore.

New Mexico Gov. Bill Richardson, a presidential candidate who has called for a dramatic reduction in the use of fossil fuels, holds between $250,000 and $500,000 in stock options from North America’s largest independent oil refiner.
