In Tempe on Thursday, Ocasio-Cortez praised Arizona voters for electing two Democratic senators. She then swiped at the state's former one-term senator, Kyrsten Sinema, who left the Democratic party to become an independent while in office and declined to seek re-election.

One thing I love about Arizonans is that you all have shown that if a US Senator isn't fighting hard enough for you, you're not afraid to replace her with one who will," Ocasio-Cortez said.

Sinema recently resurfaced old comments by Ocasio-Cortez attacking the then-senator over her refusal to abolish the filibuster, a Senate rule requiring 60 votes to pass most legislation. Last week, House Democrats implored their Senate counterparts to use the filibuster to block a Republican-drafted funding bill.

Change of heart on the filibuster I see!" Sinema posted.

Still no. In fact, the same Dems who argue to keep the filibuster for when we need it' do not, in fact, use it when we need it," Ocasio-Cortez shot back.

At their rally in Arizona, senator Bernie Sanders and congresswoman Alexandria Ocasio-Cortez offered a sharp critique of the Democrats.
