At least four different demonstrations were planned today in D.C. to protest the appointment of former Breitbart News leader Steve Bannon as President-elect Donald Trump’s chief strategist. While the first was an uneventful, if soggy, protest outside the White House, the second turned confrontational.

Two men who appeared to be property managers at the downtown building where the Republican Jewish Coalition has offices pushed and shoved a small group of Jewish protesters who showed up to urge the RJC to speak against the appointment of a notorious anti-Semite.

The demonstration was part of a national Day of Jewish Resistance denouncing Islamophobia and other forms of discrimination and criticizing some mainstream Jewish organizations’ silence on Bannon.

“The RJC has congratulated Trump on winning and has not denounced the appointment of Bannon even in the wake of all the anti-Semitic rhetoric,” protester Jenna Bluestein said. “They’ve even gone so far as to defend Steve Bannon by saying his support for Israel and the occupation should cancel out anti-Semitism, and we’re basically here to say that that’s not okay, that we need our Jewish communal institutions to stand against anti-Semitic rhetoric and other hate rhetoric.”

Around 15 protesters with IfNotNow, a Jewish activist group, marched inside the downtown building with signs. The activists were loudly but peacefully singing and speaking when two men wearing Normandy Real Estate Partners shirts shouted at the protesters, pushing them forcefully and grabbing at their signs. The activists responded by trying to shield each other and recording the incident on cellphones. It’s not clear if the two men were in any way affiliated with the RJC.

Additional security personnel declined to identify the men, only saying “they are no longer on site.”

When asked about the incident, Fred Brown, a spokesman for RJC, claimed via email that the protesters “harassed a security guard and attempted to disrupt the other tenants of the building.” He didn’t answer a question about who the men in red were, simply saying that “at no point did any member of the RJC engage with the protesters.”

Activists said nothing this forceful had ever happened to them before. “I think it’s more important than ever that we demonstrate that Jews stand up against hate and against fascism, and we call on the Republican Jewish Coalition to stand with us against Bannon, against white supremacy,” IfNotNow member Alisa Zipursky said. “We as Jews know all too well what happens when hate is institutionalized and when people are targeted based on their race, based on their ethnicity, based on their religion.”

This morning, about two dozen activists braved the rain to gather in front of the White House with signs crossed with paint, marker, and duct tape to visually “draw the line” against racism, sexism, Islamaphobia, and other forms of discrimination. Two more affiliated but separately-organized actions are planned later today in the District. At 5 p.m. activists say they will meet at the Jewish Federations of North America and protest at Malcolm X Park at 6:30 p.m.

“As the Holocaust Museum said recently, the Holocaust started not with murders, but with words,” organizer Sam Jewler said. “So it’s really important as we face a regime that seems to have very authoritarian behaviors and ideologies that people who’ve been historically marginalized—Jews and many others—stand up and reject authoritarianism, reject anti-Semitism before it turns into something much worse.”

IfNotNow members also organized local events at over 30 locations around the country.

“In D.C., we’re often seen as the place where politics happen and we’re kind of this blank stage for politicians to act upon,” said organizer Dana Fleitman. “But this is our home, this is our community, and we will be resistant to the Trump administration, we will stand up, and we will fight for Washingtonians and all people across the country.”

Activists say they are concerned about Donald Trump’s appointment of Stephen Bannon to be his chief strategist and senior counselor, and are calling on mainstream Jewish institutions to speak out against the president-elect’s apparent racist and sexist ideologies. The Anti-Defamation League has issued a statement, but several other prominent Jewish groups have declined to speak out.

“Our primary goal, from my perspective, is to alert the Jewish community and the Jewish institutions that they can’t stay quiet, that they can’t play this moderate or centrist role and play nice with this administration,” protester Lizz Goldstein said.

Before taking over Trump’s campaign, Bannon was executive chairman of the Breitbart News Network, parent company of extremist media outlet Breitbart News. With Bannon at the helm, Breitbart became a “white ethno-nationalist propaganda mill,” according to the Southern Poverty Law Center, and a platform for the white supremacist movement that has been branded as the “alt-right.”

Breitbart.com is growing in reach, now ranked as the 35th most popular website in the United States and falling just shy of the top 200 sites worldwide, according to Alexa, which bases its rankings on a combination of unique visitors and pageviews.

White supremacists have been enthusiastic about Trump’s election and cabinet member picks, saying it’s “like Christmas.“

“Instead of cozying up to power to see if it will work to our advantage, we’re going to stand out here,” organizer Noah Westreich said. “There will be more to come, because we haven’t even seen a small amount of bad yet.”

Two weeks ago about 200 IfNotNow protestors rallied in the lobby and outside of a Farragut Square office building where the president-elect’s transition team has been meeting, demanding Trump fire Bannon and renounce racism and Islamaphobia. Shortly after the protest the group said its website appeared to have been subjected to a DDoS attack.

“It’s important for me to channel my anger and the anger that everyone else has into something concrete that will show other people that there’s something to do about all the misogyny and racism,” protestor Molly Fisch-Friedman said. “It’s important if you’re angry to do something about it.”
