President Obama says an overhaul of the U.S. immigration system is just around the corner but one of the final sticking points to reform is securing the border.
On Wednesday, four of the bipartisan "Gang of Eight" senators who are pushing for reform toured the fence in Nogales, Ariz.
"What I learned today is we have adequate man power but not adequate technology," Sen. Charles Schumer, D-N.Y., said.
"With the proper use of technology we will be able to say we have a degree of border security that will enable people to move toward a path to citizenship," Sen. John McCain, R-Ariz., said.
Ironically, the four senators observed a border breach firsthand during their visit.
"Just witnessed a woman successfully climb an 18-foot bollard fence a few yards from us in Nogales," McCain tweeted.
McCain and his colleagues believe border security is a key part of reaching an immigration reform deal. The border now has nearly 22,000 agents, 651 miles of fence, 125 airplanes, and six drones patrolling the Mexican frontier.
In an interview with Univision, President Obama agreed more can still be done to secure the border.
"There's no doubt that we've improved the border security system substantially. It's never going to be 110 percent perfect," Obama said.
Still, he said border problems should not delay citizenship for undocumented immigrants.
"What we can do is continue to improve it and at the same time provide a clear pathway for those who are already here and who have invested their lives here," the president said.
Meanwhile, budget cuts have created more problems with border security and detaining illegal immigrants.
The Obama administration has released more than 2,000 illegals. Officials have also scaled back border agent hours, drug patrols, and staffing.
