Laken Riley: Marjorie Taylor Greene interrupts Biden speech

Immigration and the crisis at the US-Mexico border is one of the key issues in the US presidential election.

Both before and during President Biden's State of the Union address, Republican Marjorie Taylor Greene brought up the case of Laken Riley.

The 22-year-old nursing student was killed in Georgia in February, and police have charged an immigrant who crossed with border illegally with her murder.

"Say her name, Mr President," the congresswoman shouted in the chamber. The president did so, although on the second occasion he appeared to mispronounce her first name.
