Democratic Sen. Elizabeth Warren has demanded that Congress conduct an inquiry into the alleged ties between the administration of President Donald Trump and the Russian government.
Her call came after Trump's national security adviser, Michael Flynn, was forced to resign, according to Politico.
In his letter announcing he would step down, Flynn stated he "inadvertently briefed the Vice president-elect and others with incomplete information regarding my phone calls with the Russian ambassador."
Flynn had told Pence that he did not discuss the lifting of sanctions with the Russian ambassador on a phone call prior to Trump's inauguration.
Writing on Twitter, Warren urged an "inquiry into Russia." She added of the outgoing national security adviser: "Flynn's blinding religious hatred and shady Russian ties disqualified him as NSA on day one. His removal is a win for American values. But American national security demands that we not allow Michael Flynn to become a scapegoat for this Admin's disturbing ties to Russia."
She continued that Secretary of State Rex Tillerson "has close ties to Russia," while Commerce Secretary nominee Wilbur Ross maintains "close financial ties to Putin buddies."
She concluded by asking some questions: "When did [the White House] know that Flynn lied? What other contacts with Russia occurred during the campaign? Who knew what? Who approved what?"
Trump's Press Secretary Sean Spicer revealed Feb. 14 that the president was briefed Jan. 26 on Flynn and was told it was likely he was not being truthful about his conversation with the ambassador.
"We've been reviewing and evaluating this issue with respect to General Flynn on a daily basis for a few weeks, trying to ascertain the truth," Spicer added, according to The Telegraph.
Last week, Trump stated that he was unaware of a news report on Flynn's actions.
"The American people deserve to know the full extent of Russia's financial, personal and political grip on President Trump and what that means for our national security," House Minority Leader Nancy Pelosi added in a statement.
Trump named retired Lieutenant General Keith Kellogg as acting national security adviser. Candidates for the permanent post include Navy Vice Admiral Robert Harward and the former head of the CIA, David Petraeus.
