About a couple dozen people protested outside the U.S. Border Patrol office in Murrieta on Sunday, upset that 140 undocumented immigrants, including many children, will be flown to San Diego and then bussed to Murrieta.

The protesters waved American flags and held up signs that read, "Stop illegal immigration."

A Border Patrol union representative said agents will be taken off the streets to process all the immigrants and that the holding facility has no showers and not enough room. Union officials say the immigrants will be overcrowded while they wait to get processed.

"It's a humanitarian crisis on top of a national security issue and so on and so forth, so it's bad all the way around," said protester Douglas Gibbs. "It's bad for us and it's bad for them."

This comes after a surge of undocumented and unaccompanied Central American children flooded into the United States through the Texas border.

"We get a lot of stories … social, political, economic reasons and the increase in violence," said child immigration advocate Elizabeth Camarena. "That is what we hear over and over and groups that said violence has sent me out or pushed me out."

10News was told the immigrants coming through San Diego are all "family groups." Another group of 140 will be brought to El Centro and another group will go to Yuma, Arizona. A Murrieta Border Patrol union spokesman says planes with 140 immigrants will be coming every three days.

Officials say immigrants are being spread out to different sectors to alleviate pressure on the stations on the front lines.

President Obama calls it a "humanitarian crisis." He has already requested $2 billion in emergency funding from Congress and in an exclusive interview with ABC's "This Week," he had this message for parents south of the border.

"Do not send your children to the border," he said. "If they do make it, they'll get sent back."
