A group of House Democrats isn’t exactly giving a warm welcome to Republican Rep.-elect Mayra Flores.

The South Texas conservative activist won a special election this week for an open Rio Grande Valley House district. The 34th Congressional District special election win has spurred Republican hopes of winning more majority Latino seats in November. South Texas is a longtime Democratic bastion, and Flores’s victory, combined with competitive races in neighboring districts, suggests the party’s dominance there is fading away.

Flores’s flip specifically frustrated some House Democrats, and their frustrations played out on social media after Flores posted an inaccurate tweet.

Flores wrote, “I am the first Mexican Born American Citizen to be elected into Congress.” But the claim is not accurate. There are several lawmakers currently in Congress who were born in Mexico, though they are all men — Reps. Salud Carbajal (D-CA), Chuy Garcia (D-IL), and Raul Ruiz (D-CA). Flores will be the first Mexican-born woman elected to Congress, but not the first Mexican-born citizen, as she claimed.

Latino House Democrats took issue with the claim, including Reps. Garcia and Alexandria Ocasio-Cortez (D-NY).

Flores did not remove her inaccurate tweet but claimed she was facing attacks from the “far left” because her ancestry does not “fit their narrative.”
