President Donald Trump offered a message of “good luck” to Michael Flynn, his former national security adviser who pleaded guilty to lying to the FBI about his contacts with Russian officials, on Tuesday morning, just hours before Flynn was scheduled to be sentenced in federal court. Trump also openly expressed curiosity over what more Flynn may have to tell investigators—a line many interpreted as yet another stunning effort by the president to potentially tamper with a witness in the special counsel’s ongoing probe. Good luck today in court to General Michael Flynn.
