Apparently they didn’t get the memo that Obama is one of Morsi’s biggest backers.

A Muslim Brotherhood leader has called on Egyptians to lay siege to the U.S Embassy in Cairo to protest what he said was American support for the ouster of Islamist President Mohamed Mursi.

One person was killed and seven injured in clashes between Mursi’s supporters and opponents in Tahrir Square near the embassy and on a nearby bridge, state-run media reported yesterday, after Essam El-Erian told Muslim Brotherhood supporters that U.S. diplomats must leave Egypt without harm.

Daily protests by the deposed leader’s backers risk undermining the interim government’s plan to return to elected civilian rule. Violence at dawn today in Tahrir, the heart of the 2011 revolt that toppled Hosni Mubarak, and nearby Giza injured 19 people, the state-run Middle East News Agency reported, citing the health ministry.

In Washington, State Department spokeswoman Jen Psaki said the U.S. government was assessing the safety of American officials serving in Egypt. “We have taken steps and would take steps as needed if the situation warrants,” Psaki told reporters yesterday.
