Ben Affleck has accepted an invitation by a Republican senator to testify at a congressional hearing about a documentary film he made in the Democratic Republic of the Congo.

Affleck, in town Monday for a national hunger rally, declined to identify the senator who invited him but did say he plans to discuss what he saw at Congolese refugee camps he visited when shooting his film.

A likely host would be Sen. Richard Lugar (R-Ind.), the Senate Foreign Relations Committee
