Another lawmaker could barely stand the way Trump's transportation secretary refused to answer straightforward questions during Capitol Hill testimony on Tuesday."You are encouraging Americans to spend the summer road tripping," Sen. Patty Murray (D-WA) said to Transportation Secretary Sean Duffy during testimony on Tuesday. "Let me just ask you, how much did you rack up on gas during your Great American Road Trip?"She was referring to Duffy's controversial vacation that was reportedly bankrolled by industry giants he's supposed to regulate, including Boeing, Toyota, and Shell. Murray was pressing Duffy on how much he spent on gas because of his position that more people should road trip like him, but she was upset he would make that suggestion while gas prices rose amid the war in Iran.Duffy said he didn't know how much he racked up on gas, but he added, "I know it wasn't as much as it was under Biden."However, Murray was already trying to ask a new question, and she was clearly frustrated by Duffy's instance of making a political jab."Holy cow," she said. "Just listen."She tried to explain that "you've been recording a promo of yourself and not working to lower the cost. This show is just incredibly out of touch with where Americans are." She then pointed out that sponsors of his road trip were able to get invited to events where they'll have special access to Duffy, even though he's supposed to oversee and regulate them.Duffy had been grilled by Sen. Kirsten Gillibrand (D-NY) earlier in the hearing, and as he did with her, he responded by accusing Murray of taking money from businesses she supposedly regulates."If someone in the healthcare industry gives you $2 million, what do they get for it?" Duffy asked."I do not regulate the healthcare industry," she responded.Duffy kept repeating, "You have jurisdiction, you have jurisdiction," as Murray tried to shut him down by saying, "Mr. Secretary."He then retorted, "Welcome to MAGA," as Murray shouted, "Mr. Secretary!""Welcome to 'Drill, baby, drill,'" Duffy said. "Do you want to support lower gas prices? I welcome that. Let's drill.""Mr. Secretary, you obviously came here with a book about every one of us, so that instead of answering our questions, you can attack," Murray said over Duffy as he kept hollering about building pipelines. "You are wasting my time."
