Former Alaska Gov. Sarah Palin sent a warning Friday to Sen. Lisa Murkowski, R-Alaska, that she could face challengers in a primary race when she is up for re-election in 2022, a comment made after Murkowski was the only Republican to vote against advancing the Supreme Court nomination of Brett Kavanaugh.

“Hey @LisaMurkowski - I can see 2022 from my house…” Palin tweeted, a reference to a "Saturday Night Live" skit where Tina Fey impersonated Palin and said, “I can see Russia from my house.”

The Senate voted 51-49 on Friday morning to stop the debate on Kavanaugh, paving the way for a final vote. Murkowski voted against moving Kavanaugh’s nomination forward and claimed afterward that Kavanaugh’s “not the right man for the court at this time.”

Other conservatives also slammed Murkowski for the decision, including Fox News host Laura Ingraham.

“I like Alaska...a lot. Maybe it’s time to run for Senate after all,” Ingraham tweeted Friday morning. “@lisamurkowski has abandoned all principles of due process and fairness. Disgraceful. “#ConfirmKavanaugh.”

Kavanaugh has been accused by multiple women of sexual misconduct, including Christine Blasey Ford, who claims Kavanaugh forced himself upon her in the 1980s at a high school party, and Deborah Ramirez, who claims that Kavanaugh exposed himself to her at a college party when they were freshmen at Yale University. Kavanaugh has denied all allegations.

The FBI conducted a supplementary background check into the allegations, but Democrats have been critical of the probe and have argued that not enough witnesses were interviewed. White House spokesman Raj Shah said during an interview with CNN on Thursday morning that the FBI had interviewed nine sources.
