BREAKING: AOC shreds Sen. Kyrsten Sinema for leaving the Democratic Party, says she hasn’t offered a “single concrete value or policy she believes in” has “no goals” and “no vision” and “people deserve more.” RT IF YOU’LL FIGHT TO MAKE SURE SINEMA IS NEVER ELECTED AGAIN!

 Rep. Alexandria Ocasio-Cortez, D-N.Y. is criticizing Arizona Sen. Kyrsten Sinema after she announced her decision to leave the Democratic Party and register as an independent on Friday.

Sinema announced the decision in an Arizona Republic op-ed published on Friday, criticizing America's two party system.

"Americans are told that we have only two choices – Democrat or Republican – and that we must subscribe wholesale to policy views the parties hold, views that have been pulled further and further toward the extremes," Sinema wrote. "Most Arizonans believe this is a false choice, and when I ran for the U.S. House and the Senate, I promised Arizonans something different."

In response, Ocasio-Cortez said that Sinema doesn't offer "a single concrete value or policy she believes in."

"She lays out no goals for Arizonans, no vision, no commitments," Ocasio-Cortez said. "It’s ‘no healthcare, just vibes’ for Senate."

Ocasio-Cortez also said she's "grateful this race & nomination has opened up."

Sinema is up for reelection in 2024.

"I pledged to be independent and work with anyone to achieve lasting results. I committed I would not demonize people I disagreed with, engage in name-calling, or get distracted by political drama," Sinema said in the op-ed.

Many Democrats shrug off news of Sinema’s announcement

White House press secretary Karine Jean-Pierre called Sinema a “key partner” following her decision and said the White House has “every reason to expect that we will continue to work successfully with her.”

Sources familiar with the matter tell CNN that Sinema gave the White House a heads up that she was leaving the Democratic Party. Schumer said in a statement he also was aware of Sinema’s bombshell announcement ahead of Friday morning.

“She asked me to keep her committee assignments and I agreed,” Schumer said. “Kyrsten is independent; that’s how she’s always been. I believe she’s a good and effective Senator and am looking forward to a productive session in the new Democratic majority Senate.”

Schumer also outlined how he did not expect Sinema’s decision to impact Democrats’ plans for next year, saying in his statement, “We will maintain our new majority on committees, exercise our subpoena power, and be able to clear nominees without discharge votes.”

The Biden White House is offering a muted reaction Friday morning and insisting that they expect to continue having a productive working relationship with the senator.

One White House official tells CNN that the move “doesn’t change much” other than Sinema’s own reelection calculations.

“We’ve worked with her effectively on a lot of major legislation from CHIPS to the bipartisan infrastructure law,” the official said. The White House, for now, has “every reason to expect that will continue,” they added.

Sinema has long been the source of a complex convergence of possibility, frustration and confusion inside the White House.

“Rubik’s cube, I guess?” was how one former senior White House official described the Arizona senator who has played a central role in President Joe Biden’s largest legislative wins and also some of his biggest agenda disappointments.

There was no major push to get Sinema to change her mind, a White House official said, noting that it wouldn’t have made a difference.

“Nothing about the last two years indicates a major effort would’ve made helped – the exact opposite actually,” a White House official said.

The most urgent near-term effort was to quietly find out what it meant for their newly expanded Senate majority, officials said.

While there were still clear details to figure out about process, “I think people exhaled when we had a better understanding of what she meant,” one source familiar with the discussion said.

Democratic Sen. Amy Klobuchar of Minnesota told “CNN This Morning” that “Senator Sinema has always had an independent streak,” adding that “I don’t believe this is going to shake things up quite like everyone thinks.”

She added, “Senator Sinema has been an independent in all intents and purposes.”

‘It’s OK if some people aren’t comfortable with that approach’

Sinema and West Virginia Democratic Sen. Joe Manchin have infuriated liberals at various points over the past two years, standing in the way of Biden’s agenda at a time when Democrats controlled the House, Senate and White House.

Sinema and Manchin used their sway in the current 50-50 Senate – where any single Democrat could derail a bill – to influence a host of legislation, especially the massive $3.5 trillion Build Back Better bill that Biden proposed last year. Sinema’s objections to increasing the corporate tax rate during the initial round of negotiations over the legislation last year particularly rankled liberals.

While Sinema was blindsided by the surprise deal that Manchin cut with Schumer in July on major health care and energy legislation, she ultimately backed the smaller spending package that Biden signed into law before the election.

Both Manchin and Sinema also opposed changes to the Senate’s filibuster rules despite pressure from their Senate colleagues and Biden to change them. After a vote against filibuster changes in January, the Arizona Democratic Party’s executive board censured Sinema.

Sinema has been in the middle of several significant bipartisan bills that were passed since Biden took office. She pointed to that record as evidence that her approach has been an effective one.

“I’ve been honored to lead historic efforts, from infrastructure, to gun violence prevention, to protecting religious liberty and helping LGBT families feel secure, to the CHIPs and science bill to the work we’ve done on veterans’ issues,” she told CNN. “The list is really long. And so I think that the results speak for themselves. It’s OK if some people aren’t comfortable with that approach.”

Sinema’s announcement comes just days after Democratic Sen. Raphael Warnock won reelection in Georgia, securing Democrats a 51st Senate seat that frees them from reliance on Vice President Kamala Harris’ tiebreaking vote.

Sinema declined to address questions about whether she would support Biden for president in 2024, and she also said she’s not thinking about whether a strong third party should emerge in the US.
