"These are American citizens elected by voters in the United States of America," he added.

Luján said Trump’s focus should be on issues such as immigration and drug prices, not "picking these fights" and "saying such racist things."

Trump earlier Sunday did not identify any members of Congress by name, but the tweets came after he defended Speaker Nancy Pelosi Nancy PelosiPelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' On The Money: Anxious Democrats push for vote on COVID-19 aid | Pelosi, Mnuchin ready to restart talks | Weekly jobless claims increase | Senate treads close to shutdown deadline Trump signs largely symbolic pre-existing conditions order amid lawsuit MORE amid tensions with four progressive freshman Democrats: Reps.

Luján, a top Pelosi ally, also defended the Speaker after Ocasio-Cortez noted the insurgents Pelosi dismissed in an interview with The New York Times were all women of color.

"As a person of color ... I can tell you that Nancy Pelosi has lifted up my voice," Luján told Wallace. "I continue to look toward her leadership."

"When you have disagreements with your colleagues, you have a conversation with them," Luján said.

Luján was more evasive when asked about a tweet from the official House Democrats account blasting Saikat Chakrabarti, Ocasio-Cortez’s chief of staff, for saying Rep.

"The tone of what was included in that specific message to Sharice Davids ... was wrong and something I did not support," he said.
