DICKEY COUNTY, N.D. — Sen. Heidi Heitkamp in an interview Thursday lashed President Trump on border security, charging that the administration has failed to produce an adequate blueprint for halting illegal crossings from Mexico.

The Democrat, fighting an uphill re-election battle in this pro-Trump Republican bastion, chided the president on his signature issue, saying she has yet to see a cogent plan for fixing interior enforcement or building a wall along the southern border that will work. Heitkamp reserved some of that fire for fellow Democrats, pointedly disagreeing with liberals who dismiss concerns about illegal immigration and want Immigration and Customs Enforcement, or ICE, abolished.
