A top U.S. Justice Department official on Wednesday said the U.S. government’s crackdown on covert foreign influence has remained a “top priority” following recent court setbacks, including the acquittal of prominent Washington lawyer Greg Craig on a charge connected to his past work for Ukraine.

Speaking at a conference in Washington, Justice Department attorney Brandon Van Grack dismissed the suggestion that the U.S. government was throttling down its enforcement of the Foreign Agents Registration Act, or FARA, a decades-old law requiring the disclosure of lobbying and other advocacy activities for overseas powers.
