The measure’s “ambiguous language would ensnare American citizens and entities acting in good faith in its web of requirements and prohibitions,” the White House Office of Management and Budget said in a statement.

The House passed the measure, known as the Shield Act, on Wednesday evening. It would require political campaigns to report contacts with foreigners to the FBI and the Federal Election Commission. It would also outlaw handing private campaign information to foreigners and bolster ad-reporting requirements.

The White House called the those requirements “overly broad” and “unenforceable,” arguing elections are adequately protected under current law.
