WASHINGTON — A network of conservative activists, aided by a British former spy, mounted a campaign during the Trump administration to discredit perceived enemies of President Trump inside the government, according to documents and people involved in the operations.
The campaign included a planned sting operation against Mr. Trump’s national security adviser at the time, H.R. McMaster, and secret surveillance operations against F.B.I. employees, aimed at exposing anti-Trump sentiment in the bureau’s ranks.
The operations against the F.B.I., run by the conservative group Project Veritas, were conducted from a large home in the Georgetown section of Washington that rented for $10,000 per month. Female undercover operatives arranged dates with the F.B.I. employees with the aim of secretly recording them making disparaging comments about Mr. Trump.
The campaign shows the obsession that some of Mr. Trump’s allies had about a shadowy “deep state” trying to blunt his agenda — and the lengths that some were willing to go to try to purge the government of those believed to be disloyal to the president.
