People in the U.S. capital held aloft signs questioning President Joe Biden’s viability as a presidential candidate because of his staunch support for Israel in the nearly 100-day war against Hamas. Some of the signs read: “No votes for Genocide Joe,” “Biden has blood on his hands” and “Let Gaza live.”

Vendors were also selling South African flags as protesters chanted slogans in support of the country whose accusations of genocide against Israel prompted the International Court of Justice in the Hague, Netherlands, to take up the case.
