Sen. Marco Rubio, R-Fla., wants to hold President Trump's feet to the fire after his botched announcement that U.S. forces will pull out of Syria. Such a withdrawal would effectively hand the region over to the Russian Federation and radical Islamists in Iran. The Strengthening America's Security in the Middle East Act would not only further sanction the Assad regime as Trump delivers the brutal dictator a win, but it would also authorize more security assistance to Israel, one of our local allies hardest hit by American withdrawal, and empower states and local governments to avoid supporting the boycott, divestment, and sanctions of Israel.

Rubio's bill seems like a defiant, noble, and supposedly popular form of resistance to Trump. But the Democrats have revolted, not against Trump, but against Rubio.

Prospective Democratic presidential contender Sen. Bernie Sanders, I-Vt., took to Twitter to condemn the bill. He refused to vote for legislation that doesn't reopen the government. But it was Rep. Rashida Tlaib, D-Minn., the first member of Congress to call openly for the eradication of Israel, who let the mask slip.

"They forgot what country they represent," wrote Tlaib in response to the bipartisan bill. "This is the U.S. where boycotting is a right & part of our historical fight for freedom & equality. Maybe a refresher on our U.S. Constitution is in order, then get back to opening up our government instead of taking our rights away."

They forgot what country they represent. That's code for Jews and their alleged dual loyalties.

Shockingly, media watchdogs and champions of racial justice have maintained utter silence in the face of Tlaib's dog whistle, an anti-Semitic trope at least as old as the Persian Empire. And Democrats are increasingly falling in line with their famous freshman racists.

"Really dangerous to play politics [with] support for Israel," said Rep. Chris Murphy, D-Conn., in opposition to Rubio's dogged defense of his bill.

The merits of the bill aside, and the veracity of Rubio's charge that a "signifcant" number of Senate Democrats now support BDS aside, the lack of outrage and seeming acceptance of hackneyed attacks on Jews and Israel from Democratic politicians at the highest echelons of government is astounding. Tlaib's assertion that "they" are first and foremost loyal to Israel due to Judaism, not from a sound desire to defend our only democratic ally in the Middle East, screams of the mainstreaming of anti-Semitism in Democratic politics.

The Republican Party still must continue to condemn the white nationalism, xenophobia, and anti-Semitism that threatens to seep through the cracks of populism. The media has correctly held a spotlight to racism on the Right, and as a result, Republicans have been forced to reckon with Rep. Steve King, R-Iowa, and the standards of acceptable rhetoric. In the face of growing hatred for Jewish sovereignty and the dignity of American Jews, will Democrats and the media do the same?
