Rep. Alexandria Ocasio-Cortez, D-N.Y., gave a vigorous defense of her signature Green New Deal initiative on Friday, rejecting Republican criticism that it's socialist.

The freshman Democrat said she expected the pushback from the GOP to her plan, which calls for a complete transition to renewable energy by 2030.

"But I didn't expect them to make total fools of themselves," she told MSNBC's Chris Hayes during an "All In" town hall at the Albert Einstein Medical Center in the Bronx. "I expected a little more nuance, and I expected a little more 'concern trolling,'" meaning disingenuously expressing concern.

Ocasio-Cortez argued that the plan is economically and politically feasible and called for Congress to allow hearings on the issue.

"We don't have time for five years of a half-baked, watered-down position," she said. "This is urgent, and to think that we have time is such a privileged and removed-from-reality attitude that we cannot tolerate."

She told the audience that her mission is to use the initiative to spark a conversation beyond Washington about how to address climate change and harness the American economy to drastically reduce the effects of global warming through a national effort akin to what the country did during the Great Depression and World War II.

"The entire United States government knew that climate change was real and human-caused in 1989 — the year I was born. So, the initial response was to let markets handle it, they will do it," Ocasio-Cortez said. "Forty years of free-market solutions have not changed our position. So this does not mean that we change our entire structure of government, but what it means is we need to do something. Something!"

She said she was not concerned with convincing her fellow lawmakers or even her own party, but rather wanted to focus on going directly to voters to galvanize support.

"This is not a partisan issue, because there are Democrats who will get in the way of us saving ourselves," she said. "We encourage everyone here to look it up. I’m here not to convince my colleagues, but the electorate. ... If the electorate prioritizes it and overwhelmingly supports it, then we create the political room to pass it."

She also rejected the idea that the Green New Deal is socialist, or even radical, which has been a steady criticism of right-wing media, Republican members of Congress and President Donald Trump.

"This is not a Tea Party of the left, this is a return to representative democracy," she said. "And here's a really big difference, the Koch brothers funded the Tea Party and everyday people funded my campaign."

She added, "What I'm tired of is us worrying about the future of fossil fuels and not the future of fossil fuel workers. They wave this wand and they say it's going to cost a gazillion dollars and they sound like Dr. Evil. How about we fully fund the pensions of coal miners in West Virginia? How about we start by re-building Flint?"
