In a phone interview with BuzzFeed News on Saturday night, Loewentritt [of the GSA] — whose LinkedIn represents that he has worked at the agency since 1972 — disputed the claims made in the letter sent by the Trump campaign.

Specifically, Loewentritt said, "in using our devices," transition team members were informed that materials "would not be held back in any law enforcement" actions.
