The House Homeland Security Committee requested on Wednesday that the Defense Department inspector general investigate a $400 million contract recently awarded to Fisher Sand and Gravel Co. for constructing a portion of President Trump's border wall.

But Chairman Bennie Thompson (D-Miss.) cites another report from the Post that alleges Trump has repeatedly urged the Army Corp. to award the contract to Fisher, which is owned by a GOP donor who has made several appearances on Fox News to promote his company.
