Senate Judiciary Chairman Chuck Grassley is demanding more information from the Trump administration on Rinat Akhmetshin, the pro-Russian lobbyist who attended a controversial meeting last year with Donald Trump Jr., Jared Kushner and Paul Manafort.

Grassley announced Tuesday he has sent a letter to Secretary of State Rex Tillerson and Secretary of Homeland Security John Kelly asking for additional visa records and immigration information on Akhmetshin, who became a U.S. citizen in 2009.


Grassley said the request is part of a committee investigation into agents of the Russian government who lobbied against the Magnitsky Act but have not registered as foreign lobbyists under the Foreign Agents Registration Act.

The Iowa Republican was set to chair a hearing Wednesday on enforcement of FARA, but the session was postponed. Glenn Simpson, co-founder of the firm Fusion GPS, which commissioned a British intelligence officer to compile a now-infamous dossier on President Donald Trump, was originally slated to testify. Grassley had also said he wanted Manafort to appear at Wednesday’s hearing.

Grassley has also sought visa and parole information on Natalia Veselnitskaya, a Russian lawyer who attended last year’s meeting with the Trump campaign, which was pitched as part of a Kremlin-backed effort to help Trump win the presidency.
