Gov. Jerry Brown on Tuesday mocked Donald Trump’s plans to build a wall along the U.S.-Mexico border, saying that if Trump were to become president, California would build its own wall to defend itself.

“If Trump were ever elected, we’d have to build a wall around California to defend ourselves from the rest of this country,” Brown told labor organizers at a dinner in the state’s capital, the Sacramento Bee reported. “By the way that is a joke. We don’t like walls, we like bridges.”

Brown, 77, told members of the California Labor Federation and State Building and Construction Trades Council of California that California had benefited from immigration.

“Some of these old white guys ought to recognize that the whole pension system would collapse if we didn’t have a bunch of young people coming into this country and into this state,” he said. “They’re not all coming from here. They’re coming from other places.”

Lt. Governor of California Gavin Newsom challenged the Republican Presidential candidate to a debate about immigration in a Facebook video earlier this month, calling his immigration plan “a big loser.”

“A wall won’t secure our border or keep us safe,” Newsom says in his video. As for Trump’s idea of deporting 11 million men, women and children, Newsom cites a think tank that says the cost would amount to over $400 billion. [[372175582, C]]
