Two hours into the first hearing, focused on possible obstruction of justice by President Donald Trump, Mueller appeared to become more settled and confident.
But on several occasions he had to ask lawmakers to repeat their frequently convoluted questions. Republican members of the House of Representatives Judiciary Committee took a confrontational tone in many questions and Mueller at times responded in a wavering voice.
Each committee member had only five minutes with Mueller, often leading to rushed questions. Mueller, in turn, kept his answers short and repeatedly referred questioners to his 448-page report summarizing his 22-month investigation of Trump and Russian meddling to aid him in the 2016 U.S. election.
