On Tuesday, White House Press Secretary Sean Spicer confirmed that President Trump requested Michael Flynn’s resignation over “eroding trust,” though he acknowledged that Flynn did not break the law, and moreover it was his job to communicate with America’s foreign counterparts.
"We similarly request copies of the transcripts of Mr. Flynn’s intercepted calls and the FBI report summarizing the intercepted calls referenced in the media," the letter stated on Wednesday.
The senators also requested the delivery of "any documents containing classified information to the Office of Senate Security and provide all unclassified documents directly to the Committee."
Since 2014, relations between Russia and the European Union and the United States, deteriorated amid the crisis in Ukraine. Brussels, Washington and their allies introduced several rounds of sanctions against Russia on the pretext of its alleged involvement in the Ukrainian conflict, which Moscow has repeatedly denied. In response to the restrictive measures, Russia has imposed a food embargo on some products originating in countries that have targeted it with sanctions.
