White House reeling post Flynn resignation, Republican senators call for probe

Republican senators are seeking a probe into ties between President Donald Trump and Russia, and have called on former National Security Adviser Michael Flynn to testify.

Senator John Cornyn, who has called for an investigation into Trump's tie to Russia before Flynn resigned, said on Tuesday that the Senate standing committees with oversight of intelligence need to investigate Flynn, reports CNN.

Senator Lindsey Graham also said he wants an investigation into Flynn's conversations with a Russian ambassador about sanctions.

"I think Congress needs to be informed of what actually Gen. Flynn said to the Russian ambassador about lifting sanctions. And I want to know, 'Did General Flynn do this by himself or was he directed by somebody to do it?" the South Carolina Republican said.

Richard Burr, chairman of the Senate Select Committee on Intel, told reporters he hasn't made a decision yet on whether Flynn should testify.

Flynn resigned from his position as national security adviser Monday following reports that the Justice Department warned the Trump administration last month that he misled administration officials.

Flynn had conversations with the Russian ambassador to the United States before he was a government employee causing some to fear that he was potentially vulnerable to blackmail by the Russians.
