Good morning, Arlington! Here are five things you need to know today:

5. This Day in History: From History.com, "On this day in 1780, during the American Revolution, American General Benedict Arnold meets with British Major John Andre to discuss handing over West Point to the British, in return for the promise of a large sum of money and a high position in the British army. The plot was foiled and Arnold, a former American hero, became synonymous with the word 'traitor.'"
