Rep. Brian Mast (R-FL) said on Friday that there is a concerted network, on both the right and left, pushing antisemitic and anti-Israel ideology to the point that it has become “pervasive,” particularly among younger people.

Speaking at a Hudson Institute conference on antisemitism, Mast, the chair of the House Foreign Affairs Committee, said he does not have a “silver bullet” to address the problem because of how widespread it has become. He recounted a recent speech in a class at a military academy where he saw “probably a 50/50 divide about why we have this [U.S.-Israel] relationship, what is the benefit of this relationship?”

The Florida Republican said that he sees a “very specific network that is in place that works together to sow antisemitism that is now, in many cases, working on the left and right across the media, to go out there and put this wedge in this relationship.”

Mast described the effort as “pervasive, systematic, planned out, orchestrated” and a “very, very serious global threat across multi-national organizations, media across the globe and adversaries and terrorist organizations.”

Mast said that in response “we need to do a really good effort of showing the pervasive effort to drive this wedge — through antisemitism, is my opinion — between the United States of America and one of our greatest allies anywhere in all of these spheres — military capabilities, relationships, intelligence sharing, geography, signals intelligence, geospatial intelligence, human intelligence — all these different things that we are so close in, beyond the trust that we have.”

The Foreign Affairs Committee chair said that Europe is one of the U.S.’ “biggest adversaries” in the fight against antisemitism, describing its actions post-Oct. 7, particularly several states’ decisions to recognize a Palestinian state, as “the most unhelpful thing that could possibly be done.” He said that those efforts emboldened the terrorist groups fighting Israel.

Mast said he had not interacted much with Tucker Carlson, one of the most prominent anti-Israel voices on the right, but had a direct conversation with Carlson after the commentator attacked the congressman for his time in the Sar-El program, where he volunteered in a support capacity alongside the Israeli Defense Forces. Mast said he told Carlson he was overlooking that Mast’s ultimate loyalty is to the United States, not to Israel. 

“You never bothered to ask the question of, ‘How many countries have I taken an oath to support and defend?’ Just one: the United States of America,” Mast said he told Carlson, going on to emphasize he took that oath five times as a member of the military and an equal number as a member of the House, in addition to nearly losing his life three or four times in U.S. military service. “You’re connecting dots that don’t exist because you failed to ask some really fundamentally important questions which is, ‘Where do your allegiances lie?’”

Mast said he decided to sign up for the IDF volunteer program during Operation Protective Edge in 2014, when he faced down anti-Israel demonstrators in Boston following his time in the military.

“Some of these people draping themselves — like we see on our college campus here — draping themselves in Palestinian flags, chanting, rallying, whatever, they started harassing me and my family for being a U.S. service member,” Mast said. “At the end of that night, we got home and I told my wife, ‘I don’t know what it’s going to look like, I’m going to find a way. I’m going to show my support for Israel against this hypocrisy and against these pricks that we encountered.’”

Ken Weinstein, the former president and CEO of the pro-Israel Hudson Institute think tank, has been named ombudsman of CBS News, where he will be tasked with reviewing complaints about editorial bias from consumers and employees, Paramount announced on Monday.

The hire represents a shift for the news organization, which has faced accusations of anti-Israel bias in the wake of Hamas’ Oct. 7, 2023, attacks.

The creation of the new role also follows through on a pledge that Skydance Media had made as it sought approval from the Federal Communications Commission for its merger in late July with Paramount, CBS’ parent company.

Weinstein will report to Jeff Shell, the president of Paramount. “I’ve known him for many years and have great respect for his integrity, sound judgment and thoughtful approach to complex issues,” Shell said in a statement on Monday. “Ken brings not only a wealth of advisory experience in media and beyond but also a calm, measured perspective that makes him exceptionally well-suited to serve as our ombudsman.”

Weinstein, who is currently the Japan chair at the Hudson Institute, previously served as chair of the Broadcasting Board of Governors, now called the U.S. Agency for Global Media, from 2017 to 2020. He was nominated by President Donald Trump to serve as U.S. ambassador to Japan in 2020, but his nomination lapsed and he was never confirmed for the role in a full Senate vote.

“I am honored to serve as Ombudsman for CBS News, one of the most respected journalistic institutions in the world,” Weinstein said in a statement on Monday. “I look forward to supporting the talented team behind its reporting and to stewarding public trust in this critical institution.”

Weinstein declined to comment further on his new position.

The appointment comes amid recent reports that Skydance is now nearing a deal to acquire The Free Press and install its founder, Bari Weiss, in a senior editorial role at CBS News.
