Alaska Republican Sen. Lisa Murkowski stared down a reporter in a tense exchange that quickly went viral on social media, after she had voted in favor of President Donald Trump’s sweeping tax and domestic policy bill on July 1.

Sen. Rand Paul (R-Ky.), who voted against the bill, said Republicans could have won his vote by changing a provision related to the government’s legal borrowing limit, but they chose “pork and subsidies for Alaska” instead. Asked about Paul’s comment by NBC News, Murkowski froze and gave a reporter a death stare.
