"This is one area where I believe that there's kind of a track record of some slight disagreement between the president-elect and myself, and I say that, you know - this is it, it's not a fight - it's just a disagreement," the New York Democrat announced in a virtual town hall on Friday.
"I believe that President-elect Biden has a very optimistic view of the Republican Party. He, he has made statements on, you know, once Trump is gone, they will see the error of their ways. And I applaud his optimism but I disagree with his assessment," she went on.
Ocasio-Cortez said she was concerned about Democrats trying to "water down [COVID] relief" while they have the congressional majority to "appease Republicans."
This week, the president-elect revealed a $1.9 trillion coronavirus relief plan that includes $1,400 stimulus checks, $400 extended unemployment, state and local government funding, rental support, and a moratorium on evictions, with many other priorities.
The $1,400 together with the most recent COVID relief bill's $600 stimulus checks won't last, Ocasio-Cortez explained. "$2,000 means $2,000. $2,000 does not mean $1,400,″ she announced.
In a different tweet that came moments later, Ocasio-Cortez insisted that Congress should grant retroactive unemployment relief, in addition to the $400 per week that Biden included in his plan.
"We can't be slow walking or minimizing or hedging our ambitions because of Republicans, because this country elected Democrats and we elected a Democratic majority to get them health care, to get them stimulus checks, to get them rent protection, all of which are provisions that are included in Biden's relief plan that I'm thrilled are included in Biden's relief plan and that we look forward to expanding and building upon," the progressive firebrand said.
Biden during his campaign promoted his work across the aisle during his decades in Congress and provided Republicans a spot front and center at the Democratic National Convention.
When Biden appointed former Ohio Gov. John Kasich to speak at the DNC, Ocasio-Cortez crashed him as an "anti-choice extremist" and "not a friend to workers."
"People on the extreme, whether they're on the left or on the right, they get outsized publicity that tends to define their party," the Ohio Republican slammed back.
"You know, I listen to people all the time make these statements, and because AOC gets outsized publicity doesn't mean she represents the Democratic Party. She's just a part, just some member of it."
