Sen. Susan Collins (R-Maine) on Saturday became the 3rd Republican senator to break ranks with GOP leadership and condemn President Trump's public call for China to investigate former Vice President Joe Biden and his son, according to the Bangor Daily News.

The big picture: Collins joins Sens. Mitt Romney (R-Utah) and Ben Sasse (R-Neb.) in publicly criticizing Trump's comments, which he made just days after Democrats launched a formal impeachment inquiry over revelations that he had made the same request to the president of Ukraine.

What they're saying: Collins said it was "completely inappropriate" for Trump to invite China to investigate Biden.

"I thought the president made a big mistake by asking China to get involved in investigating a political opponent."

Between the lines: Should the House vote to impeach Trump, the Senate would host a trial to determine whether the president should be removed from office.

  • While none of the senators have said they believe Trump's actions are directly impeachable, Collins said she hopes proceedings "will be done with the seriousness that any impeachment proceeding deserves."
  • "Should the articles of impeachment come to the Senate — and right now I’m going to guess that they will — I will be acting as a juror as I did in the Clinton impeachment trial," she added.

White House aides and Senate Republicans have spent the past week readying binders full of messaging and rebuttals to guide Judge Amy Coney Barrett to a pre-Nov. 3 confirmation. "We knew for days it was going to be Amy," a Senate GOP aide involved in her confirmation process told Axios.

What we're hearing: Beyond the expected questions about her views on religion, abortion and health care, Republicans worry about Democrats painting Barrett as someone who is insensitive and unfair to “the little guy,” one source involved in the talks told Axios.

Debate commission co-chair: We don't expect moderators to fact-check candidates

Presidential Debate Commission co-chair Frank Fahrenkopf Jr. said Sunday he doesn't expect Fox News anchor Chris Wallace or any of the other moderators to fact-check President Trump or former Vice President Joe Biden at the debates.

What he's saying: "There's a vast difference between being a moderator in a debate and being a reporter who is interviewing someone," Fahrenkopf said on CNN's "Reliable Sources."
