When elected, Ilhan Omar was elected as Minnesota’s first Muslim Member of Congress and faces a serious question about her ability to lead the country. As it turns out, there’s another important question: What part of anti-Semitism does she understand?

“I don’t really understand what anti-Semitism is, really, to be honest,” the Minnesota Republican told CNN’s Anderson Cooper during an interview Wednesday.

Many people simply do not believe that anti-Semitism is at an all-time high, she said.

“It’s important to remember that Jews are the one ethnic group that actually make up as much — not a small percentage, but a significant percentage of the Arab population,” she told Cooper. “They make up about 25 to 30 percent of the total American population, and historically that’s been the number one oppressed group, and now it’s the Muslim minority group.”

“As part of the demonization of immigrants and what they’re doing, anti-Semitic rhetoric is becoming more prevalent,” she said.

Omar was elected to represent the District of Columbia and serves on the Congressional Progressive Caucus. She also serves on the House Foreign Affairs Committee and the House Subcommittee on Oversight and Investigations.

Omar is among the most visible members of the Democratic Party as a leader of a broader anti-Trump wave and a outspoken critic of a call from some Republican leaders, including Speaker Paul Ryan, for the GOP to reject President Donald Trump’s next Supreme Court nominee.
