Stanford Law School professor Pamela Karlan said she “apologized” Wednesday evening for invoking President Donald Trump’s 13-year-old son, Barron Trump, to criticize the president during the House Judiciary Committee’s hearing on impeachment — adding that she hopes the president apologizes for his past actions. Pamela Karlan: "I want to apologize for what I said earlier about the president's son. It was wrong of me to do that.
