"I wish I could tell you...that I am shocked. I am not," Sanders, a 2020 Democratic presidential candidate, said of President Donald Trump's support for Israel's decision. "We have a president who, tragically, is a racist, is a xenophobe, and who is a religious bigot."

On Friday morning, the New York Times reported that Israel will allow Tlaib to visit her 90-year-old grandmother who lives in the occupied West Bank. Israel did not change its position on Omar.

Sanders said Thursday that "the idea that a member of the United States Congress cannot visit a nation which, by the way, we support to the tune of billions and billions of dollars is clearly an outrage."

"And if Israel doesn't want members of the United States Congress to visit their country to get a firsthand look at what's going on—and I've been there many, many times—but if he doesn't want members to visit, maybe [Netanyahu] can respectfully decline the billions of dollars that we give to Israel," Sanders added.

Progressives applauded Sanders' remarks, noting that the senator's willingness to challenge U.S. military aid to Israel makes him unique in the 2020 Democratic presidential field.

"People have been asking how Bernie can distinguish himself from rivals who at least profess agreement on domestic issues," tweeted HuffPost reporter Daniel Marans. "This is one area where the distinction is clear."

Rep. Alexandria Ocasio-Cortez (D-N.Y.) called the Vermont senator's statement "a big deal."
