Republican US lawmakers tried on Wednesday to pick apart President Joe Biden's defense of his withdrawal from Afghanistan as they attacked his judgment and honesty during a second day of contentious Congressional hearings with Pentagon leaders.<br /><br />Democrat Biden has faced the biggest crisis of his presidency over the war in Afghanistan, which he argued needed to be brought to a close after 20 years of stalemated fighting that had cost American lives, drained resources and distracted from greater strategic priorities.<br /><br />Republicans have accused him of lying about military commanders' recommendations to keep 2,500 troops in the country, playing down warnings of the risks of a Taliban victory, and exaggerating America's ability to prevent Afghanistan from again becoming a safe haven for militant groups like al Qaeda.<br /><br />-Reuters -
