Lawmakers urge reversal after financier says visa revoked

WASHINGTON -- Republicans and Democrats are demanding answers from the U.S. government after British-American financier William Browder said his visa was revoked.

Browder lobbied for a law named after his former employee, Russian whistleblower Sergei Magnitsky, that imposed travel bans and froze assets of dozens of Russian officials. Magnitsky died after accusing Russian officials of stealing government money in a tax fraud scheme.

Browder tweeted Sunday that his name had been added to an Interpol travel list and his U.S. visa had been revoked.

Senate Armed Services Committee Chairman John McCain and Maryland Sen. Ben Cardin said Monday that Browder is a "strong advocate for anti-corruption efforts" and asked the Homeland Security Department to review the decision.

New York Rep. Eliot Engel called on the State Department to reverse its "baffling decision."
