Et tu, Paul Ryan?

That’s what President Trump may be thinking if Maxine Waters has her way.

The California congresswoman appeared on “The Breakfast Club” radio show on Monday and predicted that Trump will be impeached “by December,” effectively asserting that Republicans will turn on him while they are still in the majority and seek his ouster from office.

“So I believe it is possible to impeach him,” Waters said.

“How long is it gonna take? I don’t know. But I give it to about December,” she added.

When challenged, she doubled down.

“I give it till December. Our new special counsel, Mr. Mueller,” she said, mispronouncing his name, “has impaneled a grand jury as you know.

“And they can be involved with investigations and they can do indictments also,” she said.

“So little by little, drip by drip, it’s happening,” Waters said.

Last week, she said she won’t stop with Trump’s impeachment — she’s gunning for Vice President Mike Pence, too.

While Waters was yukking it up with the ladies on “The View” on Friday, she said Democrats are going to go after “Putin” next.

She apparently meant to refer to the vice president.

“Do you think Pence will be better than Trump if he were impeached?” Joy Behar asked.

“No, and when we’re finished with Trump, we have to go and get Putin,” Waters responded.

“Putin or Pence?” Behar asked.

“Uh, Pence,” Waters said.

“We’ll get two-for-one with Trump and Putin, and then go after Pence,” Behar said.
