Sen. Susan Collins (R-Maine) told CNN's "State of the Union" Sunday she was "appalled" to see her colleague Sen. Mitt Romney (R-Utah) booed and nearly censured at the Utah Republican Party state convention a day earlier.

Why it matters: The effort to censure Romney for his vote to convict former President Donald Trump following the Jan. 6 riot at the Capitol failed by a 711-798 vote. A number of Republicans have faced backlash in their home states for voting to convict Trump, as the former president continues to have significant sway over the party.

What they're saying: "Mitt Romney is an outstanding senator who serves his state and our country well,"Collins said Sunday. "We Republicans need to remember that we are united by fundamental principles."

  • "We are not a party that is lead by just one person. There are many prominent upcoming younger men and women in our party who hold great promise for leading us."
  • "[T]he person who agrees with 70 or 80% of the time is your friend, not your enemy."
A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

Of note: Collins also defended Liz Cheney, who was censured by the Wyoming GOP for her vote against Trump.

  • "Liz Cheney is a woman of strength and conscience, and she did what she felt was right, and I salute her for that. We need to be accepting of differences in our party."

Obama plans birthday bash amid COVID concerns

Former President Obama is hosting a 60th birthday bash for himself and hundreds of guests on Martha’s Vineyard this coming weekend amid heightened public health concerns — locally and nationally — about the COVID-19 Delta variant.

Why it matters: The recent breakthrough cases in nearby Provincetown, Massachusetts, after the July Fourth holiday showed the continued risk of spread even between vaccinated people — prompting new masking guidelines from the CDC.

U.S. will give Russians written response to NATO demands, Blinken says

Secretary of State Antony Blinken confirmed after a meeting with his Russian counterpart on Friday that the U.S. will provide written answers to Russia's security demands next week.

Why it matters: Russia claims to be waiting for "concrete answers" to its demands that NATO rule out further expansion and roll back its presence in eastern Europe before deciding its next steps on Ukraine. But the U.S. and NATO have called those proposals "non-starters," and Friday's meeting offered no breakthroughs, so it's unclear how written answers might change the equation.

More surprises await scientists at Antarctica's "Doomsday Glacier"

Researchers like David Holland, an atmospheric scientist at New York University, are in a race to understand the fate of a massive glacier in West Antarctica that has earned a disquieting nickname: "The Doomsday Glacier."

Why it matters: Studies show the Thwaites Glacier (its official name) could already be on an irreversible course to melt during the next several decades to centuries, freeing up enough inland ice to raise global sea levels by at least several feet.
