Democratic presidential candidate Sen. Cory Booker (N.J.) launched what he calls a "Justice for All" campaign tour over the weekend, but his kickoff speech was interrupted by protestors shouting "Justice for Palestine."

What are the details?

Booker was speaking to a crowd in his adopted hometown of Newark on Saturday, when activists began shouting "Justice for Palestine" and "from Palestine to Mexico, borders have to go." The 2020 hopeful ignored the distraction while supporters began a counter-chant of "Cor-y, Cor-y."

Most of the approximately one dozen interlopers were shuffled out of the venue after their initial disruption, but a few stayed behind and continued to antagonize Booker while he met with supporters after the rally, Yahoo News reported.

One protestor, Wajeeh Abushawish, mocked Booker's tour slogan speaking with Yahoo, telling the outlet, "You say 'Justice for All' and he named, you know, clean water, housing, affordable health care, freedom but he doesn't ... talk about Palestine. They're struggling just as much as us here — even more."

Another activist claimed, "Booker actively supports the oppression of Palestine."

Yahoo reported all three of the protestors who spoke with the outlet declared their support for Vermont Sen. Bernie Sanders in the 2020 Democratic presidential primary, with Abushawish yelling, "Bernie 2020!"

Anything else?

According to NJ.com, Booker is the only Democratic presidential candidate to co-sponsor new legislation called the Israel Anti-Boycott Act, which would oppose the "Palestinian-led boycott, divestiture and sanctions movement, better known as BDS, which does not support Israel's right to exist."

Booker also attended the American Israel Public Affairs Committee's conference last month, Fox News reported, in spite of a warning from liberal group MoveOn.org calling on Democrats to boycott the AIPAC event entirely.
