U.S. lawmakers grilled Trump administration officials Tuesday about the war in Afghanistan, saying the new White House strategy was inconsistent and was not producing results.
The comments made at a Senate Foreign Relations Committee hearing reflected growing frustration in Congress about the U.S.-led war, which is entering its 17th year.
​As recently as November, General John Nicholson, the top U.S. commander in Afghanistan, acknowledged that the conflict remained a stalemate.
Since then, a wave of high-profile insurgent attacks have rocked the capital, Kabul. The Taliban now controls or contests almost half the country, according to latest U.S. estimates.
Despite the setbacks, U.S. Deputy Secretary of State John Sullivan, who is helping oversee the new White House strategy, gave a positive assessment of the conflict.
"The president's South Asia strategy is showing some signs of progress," Sullivan said. "On the battlefield, we are seeing the Taliban's momentum begin to slow."
But lawmakers from both parties expressed skepticism.
"Something is clearly not working," said Senator Ben Cardin, a Maryland Democrat and longtime Afghan war critic. "By any standard, the current security situation is grim."
Some lawmakers took aim at President Donald Trump, who last week said he didn't want to talk with the Taliban — a statement that seemingly contradicted his own strategy.
After Sullivan and a top Pentagon official told the lawmakers that the U.S. was in fact still open to negotiations with the Taliban, lawmakers pressed for more details.
"You can see that the world and those involved in the peace process may be pretty confused about what the U.S. position is. What is it?" asked Senator Chris Murphy, a Connecticut Democrat.
Sullivan said he thought Trump was expressing a reaction to last month's terrorist attacks, and was pointing out that "significant elements of the Taliban are not prepared to negotiate."
"And it may take a long time before they are willing to negotiate," he added.
But many in the Senate appear tired of waiting, and that impatience was on display Tuesday.
