Several protests marked the beginning of the week, including the March for Science on Saturday and a "smoke-in" by a pro-marijuana group on Monday.
On Wednesday, senators boarded buses for a briefing on North Korea down Pennsylvania Ave. at the White House. And Thursday marked the annual Take Our Daughters and Sons to Work Day.
