Republican Rep. Cathy McMorris Rodgers barely survived a primary -- now she wants to impeach Rod Rosenstein

Rep. Cathy McMorris Rodgers (R-WA) is the fourth highest Republican in the House leadership, yet in her primary election Tuesday, she is barely leading her Democratic challenger, by just 500 votes. But a tape obtained by MSNBC's Rachel Maddow Wednesday might change everything.

According to Maddow, Rodgers held a high-dollar fundraiser headlined by Rep. Devin Nunes (R-CA). Someone purchased a ticket to the event to record what Nunes said behind closed doors. What was captured was a striking admission that the GOP has a plan ready to execute to get rid of deputy Attorney General Rod Rosenstein to shut down the Mueller investigation.

"The Senate would have to drop everything they're doing ... and start with impeachment on Rosenstein. And then take the risk of not getting Kavanaugh confirmed," Nunes said. "So it's not a matter that any of us like Rosenstein. It's a matter of, it's a matter of timing."

In her Wednesday show, Maddow noted that Rodgers seems as though she's in "real danger" of losing her seat in November. It's something Maddow said is unheard of for someone as high up in the leadership as she is.

"Well, now when her constituents decide whether or not to return her to Washington, they'll also have this to chew on in addition to everything else they already know about her," Maddow said.

Before the August recess, some tea party members filed their articles of impeachment for Rosenstein, but Speaker Paul Ryan said that the Congress had no intention of moving forward with impeachment.

The recording of Nunes has Rodgers chiming in to agree when Nunes said that there was a "live Republican plan to impeach Rod Rosenstein," Maddow explained. "They don't want it to seem like they're pursuing it now. They're waiting for two important things to happen first and then their plan is to go ahead."

The recording reveals that they want the Supreme Court nominee to be confirmed and the election to be over. Rodgers cuts in to explain that the Senate would also have to start the impeachment proceedings.
