Sen. James Lankford said Sunday President Trump's conversations with former FBI Director James Comey appear "more like an inappropriate conversation than obstruction" of justice.
"I would say it's very inappropriate," Lankford, R-Okla., told John Dickerson of CBS' "Face the Nation."
"As Jim Comey said, it's awkward to be able to have the president of the United States sitting down with someone in the FBI, the leadership of the FBI, to be able to have direct questions. And for the issue to come up about the Michael Flynn investigations — inappropriate," Lankford added. "So this looks more like an inappropriate conversation than obstruction."
Lankford is a member of the Senate Intelligence Committee that heard Comey's testimony about the Trump conversations last week.
Comey testified the president said he hoped the FBI would end the bureau's investigation of Mike Flynn, Trump's first national security adviser.
In the testimony, Comey acknowledged he purposely leaked to a friend memos he wrote documenting the Trump conversations hoping it would lead to the appointment of a special counsel. The Department of Justice soon after appointed Robert Mueller to lead the Russia investigation.
Lankford criticized Comey's decision to release the memos. But he said the memos being public does not damage national security.
"Releasing his memos is not damaging to national security," Lankford said. "Now, is it appropriate? No, it's not. That was inappropriate of him to do."
