49ers wide receiver Anquan Boldin spent Monday in Washington D.C. meeting with congressional leaders and the White House about injustices he witnessed in Africa.

Boldin was on a mission to Africa when the 49ers traded a sixth-round pick to the Ravens for Boldin just before April’s NFL draft.

Boldin was on Capitol Hill as part of Oxfam America, an organization that seeks to address poverty and injustice in 90 countries. Boldin visited Senegal this spring and was in Ethiopia last year with former Ravens teammates Torrey Smith and Ray Rice.

Organizations are lobbying the White House and Congress this week before President Obama’s goodwill tour of Senegal, South Africa and Tanzania.

In Senegal this spring, Boldin grew concerned about gold mining by multinationals.

“You have these people who literally live on top of gold mines … and they see no benefits from it,” said Boldin, who met with poor farmers in remote parts of Senegal. In Washington, Boldin met with White House officials, a senior aide of House Minority Leader and San Francisco Representative Nancy Pelosi, along with Rep. Chris Smith (R-N.J.) and Senators Marco Rubio (R-Fla.) and Jeff Flake (R-Ariz).

“People definitely get it,” Boldin told Rollcall.com. “But I think it’s an issue that definitely needs to continue to be pushed.”
