Lindsey Graham’s sister, Darline Graham Nordone, has been named as her late brother’s temporary replacement in the U.S. Senate after his unexpected death over the weekend.

At an appearance at the Chicago Council on Global Affairs on Monday, Republican Sen. Lindsey Graham from South Carolina said President Obama should have pushed ahead with military strikes in Syria to send President Bashar al-Assad and other dictators an important signal. Paris Schutz has the details.
