Minority Leader Chuck Schumer said Democrats are demanding that former senior national security adviser Mike Flynn answer questions about his conversations with the Russian ambassador and possibly other officials in Moscow in public and under oath.

“We’re demanding that campaign and transition officials be made available to testify in public, under oath on these issues,” Schumer told reporters Wednesday afternoon. He noted that Flynn and Paul Manafort, who served as a top Trump campaign aide, have both reportedly had constant contact with Russian intelligence officials.
