Sen. Jacky Rosen (D-NV) has been among the most vocal Democrats in support of Israel in the Senate, even breaking with President Joe Biden and Senate Democratic leadership when she feels her party isn’t taking a muscular enough approach in the Middle East.

But Sam Brown, the Republican Senate candidate challenging Rosen in Nevada, is nonetheless attempting to paint her as insufficiently supportive of the Jewish state, even invoking the congresswoman’s Jewish faith in a recent attack.

“Here’s one of her greatest offenses: As a Jewish woman in the Senate, she has not stood up and pushed back against [President Joe] Biden or even [Senate Majority Leader] Chuck Schumer [D-NY] as these Democrat leaders have done nothing but insult Prime Minister [Benjamin] Netanyahu and have hindered Israel’s ability to prosecute this necessary war against Hamas,” Brown said in a radio interview with Mark Levin, a top conservative host, on July 10.

It’s not the first time Brown has advanced such an attack against Rosen, claiming she’s failing to aggressively stand up for Israel.

Rosen has been among the most stalwart Democratic supporters of Israel in the Senate since Oct. 7, often calling for a more hawkish approach than the administration has taken on a range of issues, including distancing herself from the administration’s pause on arms transfers to Israel and Schumer’s call for Netanyahu’s ouster.

“Senator Rosen takes a back seat to no one when it comes to her ironclad support for Israel’s right to defend itself and an unbreakable U.S.-Israel relationship, even when it means standing up to her own party,” Rosen spokesperson Joe Bush said.

Levin, who is Jewish, went on to praise Brown in the interview, saying, “You’re literally running against a leftist in the Democrat Party who’s born Jewish and your credentials in supporting the state of Israel are far superior to hers. It’s really amazing when you think about it, isn’t it?”

Rosen is a former president of her synagogue, the first lawmaker who has held that role and later been elected to the U.S. Senate.

Brown responded, “It really is,” adding that “we’re at a time and place now where words don’t matter,” and slamming Rosen for voting against “a bill that would support Israel.”

Brown appeared to be referring to House-passed legislation that would have provided aid to Israel with an accompanying cut to funding to the Internal Revenue Service without support for Ukraine and other allies, a bill that was opposed by the administration and most congressional Democrats.

In a statement to JI, a spokesperson for Brown’s campaign did not address his mention of Rosen’s religion, but largely reiterated the other points he made in the interview.

“Jacky Rosen has joined Senate Democrats in rejecting standalone aid packages to Israel over and over and over again. And she barely uttered a peep when Chuck Schumer attempted to undermine Netanyahu and Israel’s democratic election process,” Brown’s communications director, Kristy Wilkinson, said in a statement. “Words without action are meaningless.”

The Brown campaign did not respond to a question requesting the specific examples Brown was referencing in the interview.

Brown’s attacks on Rosen’s record on Israel are a change from his comments earlier in the race, when, speaking to JI a year ago, he drew few contrasts with Rosen’s record on Israel and offered no negative commentary, instead describing her as an ally of the Jewish state and emphasizing the bipartisan nature of the issue.

Since Oct. 7, Rosen has also pushed the administration to freeze funds it had released to Iran, pressed the administration to provide additional Iron Dome batteries to Israel and broke with Democratic leadership to vote to provide the U.S. military the authority to counter Iranian-backed militias in Iraq and to maintain the U.S. authorization for military force in Iraq until the Iranian-backed militia threat in Iraq and Syria has ended, in addition to a range of other letters and legislation to support Israel and combat antisemitism.

Brown’s comments mentioning Rosen’s Judaism echo sentiments that have become a frequent talking point for former President Donald Trump, who, with increasing frequency, while on the campaign trail has called out Jewish Democrats for what he says is their alleged lack of support for Israel.

Trump has routinely lambasted Jewish voters who support Democrats, saying they’re “fool[s]” and “should have their head examined,” has described Schumer as “a Palestinian” for allegedly abandoning Israel and most recently appeared to agree with a Jewish radio host last week who called Second Gentleman Doug Emhoff “a crappy Jew.”

In that same interview, the former president declared that Vice President Kamala Harris, who is married to Emhoff, “doesn’t like Jewish people.”
