President Obama will send up to 1,200 National Guard troops to the Southwest border and increase spending on law enforcement, yielding to demands from both Republican and Democratic lawmakers there that border security be tightened, administration officials said.

That was the opening of an article in the New York Times. Here are additional excerpts:

Homeland Security officials said that the troops would provide support to law enforcement officers already working along the border by helping observe and monitor traffic between official crossing points, and would help analyze trafficking patterns in hopes of intercepting illegal drug shipments. They performed similar tasks in an earlier deployment along the border from 2006 to 2008, when they also assisted with road and fence construction. The troops have not been involved directly in intercepting border crossers.

In addition to the soldiers, the White House said it would request $500 million in supplemental funds to pay for more federal agents, prosecutors, investigators and technology at the border.

Homeland Security officials have said that they have significantly increased border security efforts since Mr. Obama took office. Homeland Security Secretary Janet Napolitano, a former governor of Arizona, said last month that the border was “as secure now as it has ever been,” though she conceded there was room for improvement. Critics on the right derided her remarks as out of touch.
