WASHINGTON — Defense officials say the Department of Homeland Security has asked the Pentagon to fund the construction of 270 miles of border wall this year as part of a counter-drug effort. 

The officials say the request came in Wednesday, and the Pentagon is beginning what will be a two-week assessment to determine what will be approved. 

The officials would not provide any cost estimates.
