Sen. Jeff Flake Jeffrey (Jeff) Lane FlakeRepublican former Michigan governor says he's voting for Biden Maybe they just don't like cowboys: The president is successful, some just don't like his style Bush endorsing Biden? Don't hold your breath MORE (R-Ariz.) says that Republicans should have serious concerns if the details of former FBI Director James Comey’s memo about President Trump are true.

“I don’t want to characterize it,” he told ABC News Wednesday. “But Republicans can’t be OK with this.

“If it is as we fear, if the president did pressure him to get rid of the investigation and later fired him, then obviously Republicans ought to be concerned.”

Flake was asked if Comey’s memo described “possible obstruction of justice” from Trump.

The New York Times on Tuesday reported that a memo from Comey said the president had asked him to end the federal probe into former national security adviser Michael Flynn in February.

Comey wrote in a memo shortly after the meeting with Trump that the president told him, “I hope you can see your way clear to letting this go, to letting Flynn go.”

The meeting took place Feb. 14, one day after Flynn resigned, according to the Times, which said Comey’s memo was part of his effort to create a paper trail about what the former director saw as Trump's improper influence on the Flynn investigation.

The Senate Intelligence Committee has since sent Comey a request to testify publicly.

Comey declined the panel’s first invite last week, reportedly preferring public testimony to meeting with members behind closed doors.

Trump later undercut that explanation, citing the “made up story” about his ties to Russia as a factor.

The FBI is probing Russian meddling in the 2016 presidential election, including possible ties between Russia and members of Trump’s campaign, such as Flynn.
