Rep.-elect Alexandria Ocasio-Cortez (D-N.Y.) hit back Tuesday via Twitter at Republicans who claim she “doesn’t know what she’s talking about.”

Conservatives have repeatedly insulted the incoming progressive lawmaker in recent weeks, with many using derogative statements to question whether she is up to the job.

Ocasio-Cortez issued witty retorts to each of those attacks.

On Tuesday, she appeared to respond to the general criticism with this post:

Republicans: “She doesn’t know what she’s talking about!”

In the tweet, which has now gone viral, Ocasio-Cortez ridiculed the Republicans who are attacking her by highlighting an embarrassing gaffe made by one of their own, white supremacist Rep. Steve King (R-Iowa).

King complained during Google CEO Sundar Pichai’s Tuesday House Judiciary Committee hearing that his granddaughter had found an unfavorable rendering of him while playing a kids game on an iPhone

Pichai was forced to remind him, however, that: “Congressman, iPhone is made by a different company.”
