The Office of Government Ethics told a Democratic lawmaker in the letter that the White House is probing whether a $184 million loan from the real-estate arm of Apollo Global Management APO, -0.56% nd a $325 million loan from Citigroup Inc. C, +0.24% may have run afoul of the rules and laws governing the conduct of federal employees.

Both loans went to the Kushner Cos., the private real-estate company founded by Kushner’s father and run by members of his family. Kushner, who is President Donald Trump’s son-in-law and serves in a senior position in the White House, met with top executives of both Citi and Apollo before each loan was disbursed, the New York Times reported last month.
