In her roughly three-minute speech, Ocasio-Cortez declared that the ongoing partial government shutdown is not about the president's demands for border wall funding but “the erosion of American democracy.”

“It is actually not about a wall, it is not about the border, and it is certainly not about the well-being of everyday Americans,” the first-year congresswoman said. “The truth is, this shutdown is about the erosion of American democracy and the subversion of our most basic governmental norms.”

”It is not normal to hold 800,000 workers’ paychecks hostage. It is not normal to shut down the government when we don’t get what we want,” she continued. “And it is certainly not normal to starve the people we serve for a proposal that is wildly unpopular among the American people.”

Her comments came on the 26th day of the shutdown.

Ocasio-Cortez has been a media sensation since her stunning primary upset of 10-term Democratic Rep. Joseph Crowley in New York's 14th Congressional District.

The progressive star, known for her social media savvy, has built her Twitter following to more than 2.44 million as of Thursday.
