After retired Lt. Gen.Michael T. Flynn's resignation from his position as national security adviser, Democratic lawmakers are once again urging further investigation into President Donald Trump's cabinet and its relationship to Russia.
"General Flynn is doing the right thing by stepping down. However, far too many questions remain unanswered about this administration's ties to Russia," Democratic Rep. Eliot Engel of New York, the ranking member of the House Foreign Affairs Committee, said in a statement.
"We need a thorough, bipartisan investigation to get the complete picture of Russia's interference in our election, and Congress needs to take steps, such as passing my SECURE Our Democracy Act, to punish those responsible," Engel added in reference to legislation he introduced after Democratic presidential candidate Hillary Clinton lost, which sought to "expose and deter unlawful and subversive foreign interference in elections for Federal office, and for other purposes," according to GovTrack.
Democratic Rep. Joaquin Castro of Texas, once considered a potential vice presidential pick during the Clinton campaign, also urged further investigation.
"General Flynn's resignation is a step in the right direction. But many questions remain," he tweeted.
Democratic Rep. John Dingell of Michigan was more direct and even referred to the leaked dossier of unsubstantiated claims about Trump's relationship to Russian officials.
"Flynn's resignation CANNOT be end of the story," Dingell tweeted. "Who talked to who When? Who knew? When? How far up did it go? How much of dossier true?"
Flynn resigned after The Washington Post revealed he had conversations with a Russian ambassador concerning U.S.-imposed sanctions one month before Trump took office, and then reportedly lied about it to Vice President Michael Pence.
"Unfortunately, because of the fast pace of events, I inadvertently briefed the Vice President Elect and others with incomplete information regarding my phone calls with the Russian Ambassador," Flynn wrote, according to Fox News. "I have sincerely apologized to the President and the Vice President, and they have accepted my apology."
