Under Obama, border apprehensions have fallen from their high points. Border apprehensions
peaked at almost 1.7 million in 2000 under President Clinton, and apprehensions in 2011 were at the lowest level since 1970. The post-2008 declines are due to the recession and loss of jobs which had attracted unauthorized immigrants. Net illegal immigration from Mexico has fallen to zero or even fewer coming than leaving.
Expert analysis
We sent Wasserman Schultz's claim to immigration experts. No one disputed the border patrol numbers, but they also pointed to other factors when examining changes in border security that provide a more complex picture.
"Yes, the number of Border Patrol agents is at an all-time high," said Rey Koslowski, an expert on the border and an associate professor of political science and public policy at the University at Albany. "Whether that equates to 'border security' is another question. As to who should get more credit for border security, the fence was a bipartisan project."
Christopher Wilson, an associate with the Wilson Center's Mexico Institute and an expert on border management, noted that border patrol agents don't precisely equal
border security.
"In the end, though, you can't deploy border security, it must be something that is achieved. This gets into one of the major problems with the whole border security debate—the lack of an accepted definition of the term."
Our ruling
Wasserman Schultz said, "President Obama has the most border patrols and border security deployed at the border of any previous president."
She is correct that the highest number of border patrol agents has been under Obama: there were 21,444 in 2011. Wasserman Schultz was careful here and said "most" and didn't talk about the growth rate. But it's worth noting that the big growth was during Bush's tenure: between 2001 and 2009, the number of agents posted nationally rose from about 9,800 to a little more than 20,000.
Other border security measures are not as simple to quantify. The key piece of infrastructure -- the fence -- was launched under Bush. Work on the fence and other border security improvements continued under Obama.
We rate this claim Mostly True.
