Which of the following details about the bill is INCORRECT?

The marchers chanted "Si se puede", a Mexican-American rallying cry that means "yes, we can". They hope to block a bill already passed by the House of Representatives that would make it a felony to be an illegal immigrant in the United States. The bill, which is not yet law, would also penalize those who help or hire illegal immigrants, and erect fences along one-third of the U.S.-Mexico border. A spokesman for the Los Angeles Police Department says about 500,000 people marched Saturday.
