Rep. Alexandria Ocasio-Cortez (D-NY) took Trump campaign national finance committee chairwoman Kimberly Guilfoyle to task for claiming Monday evening at the Republican National Convention that her mother — who was born in Puerto Rico — was an “immigrant” to the United States, remarking:

“As a first generation American I know how dangerous their socialist agenda is.

“My mother Mercedes was a special education teacher from Aguadilla, Puerto Rico. My father, also an immigrant, came to this nation in pursuit of the American dream.”

However, there’s just one problem with Guilfoyle’s assertion of being from an immigrant family: Puerto Rico is a U.S. territory, so that means her mother was an American citizen from birth, as AOC reminded her on Twitter:

Others also wondered if Guilfoyle had even the slightest clue about anything she railed about as she shouted out her address on Monday evening:

Guilfoyle’s mistake might not be such a big deal if it wasn’t reflective of a larger problem in the Trump administration: Lying. President Donald Trump has told tens of thousands of lies since taking office and constantly lies on social media.

Sorry, Kimberly, but we can’t cut you any slack because you should know better and also because you hang out with pathological liars.
