YOU’RE UP, TILLERSON: Former Exxon Mobil leader Rex Tillerson takes the hot seat today at 9:00 a.m. as he seeks to become the top U.S. diplomat. Tillerson will face aggressive questioning on everything from his close ties to Russia, Exxon’s complex history on climate change and how he would tackle international climate diplomacy as secretary of State. “I’m deeply interested in the record of Exxon Mobil when Mr. Tillerson was in leadership in funding organizations that tried to muddy up or deny the reality of climate science,” former Vice Presidential nominee Sen. Tim Kaine (D-Va.) said in a Tuesday interview. POLITICO’s Burgess Everett has a run-down of what to watch for at today’s hearing. If you go: The hearing kicks off 9:00 a.m. in Dirksen 106.
