Rep. Alexandria Ocasio-Cortez’s first speech on the House floor Wednesday quickly made C-SPAN history.

“In just over 12 hours C-SPAN tweet of @RepAOC floor remarks last nite have become most-viewed twitter video by @cspan of any remarks by a member of House either party. 1.16M,” Howard Mortman, the broadcaster’s communications director, posted Thursday on Twitter, and linked to the video of her speech.

The most viewed C-SPAN Twitter video in the Senate was of Sen. Kamala Harris grilling Brett Kavanaugh, President Trump’s nominee to the Supreme Court, during his contentious confirmation hearing last October, he said.

Her video got 7.14 million views, Mortman said.

Ocasio-Cortez, 29, who was sworn in to Congress Jan. 3 after defeating incumbent Joe Crowley in last June’s Democratic primary, noted the sharp increase in her Twitter followers since she ran for office.

“‘What is my life’ is one common thing that could be said about both my life a year and a half ago when I was campaigning from a restaurant w/ ~300 Twitter followers and now,” she posted Thursday.

She now has 2,444,298 followers on Twitter and 1.8 million followers on Instagram.

Her exposure on social media has grabbed the attention of her opponents.

The American Immigration Control Foundation launched TV ads nationally on social media and TV networks blasting her for wanting to abolish Immigration and Customs Enforcement.

In a release announcing the ad rollout, the group noted that Ocasio-Cortez “generated media buzz” when she called for getting rid of the agency and now “other Democrats have echoed” her calls.

In her House speech, Ocasio-Cortez blasted the government shutdown and Trump’s demand for a border wall.

“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,” she said. “The truth is, this shutdown is about the erosion of American democracy and the subversion of our most basic governmental norms.”
