“Rep. Michael Waltz (R-FL) said Sunday that he has met with President Joe Biden’s National Security adviser Jake Sullivan — and that the two administrations are working collaboratively on national security issues during the transition,” Politico reports. Said Waltz: “Jake Sullivan and I have had discussions, we’ve met. For our adversaries out there that think this is a time of opportunity, that they can play one administration off the other — they are wrong.”
