WASHINGTON (AP) — Dr. Anthony Fauci, the government’s top infectious diseases expert, blasted Sen. Ted Cruz for suggesting that Fauci be investigated for statements he made about COVID-19 and said the criticism by the Texas Republican was an attack on science.

“I should be prosecuted? What happened on Jan. 6, senator?” Fauci, who is President Joe Biden’s chief medical adviser, said in an interview that aired Sunday on CBS’ “Face the Nation.” It was a reference to the violent insurrection at the U.S. Capitol by supporters of then-President Donald Trump that was stoked as Cruz helped lead GOP objections to Congress’ certifying the 2020 election results.
