The Trump administration said Tuesday that it was revoking the security clearances of 37 current and former national security officials in the latest act of retribution targeting public servants from the federal government’s intelligence community, Associated Press reported.

A memo from Director of National Intelligence Tulsi Gabbard accuses the singled-out individuals of having engaged in the “politicization or weaponization of intelligence” to advance personal or partisan goals, failing to safeguard classified information, failing to “adhere to professional analytic tradecraft standards” and other unspecified “detrimental” conduct. 

The memo did not offer evidence to back up the accusations, according to Associated Press.
