7 things to know now: Trump, Clinton at forum; 9/11 flag; Lochte suspended

1. National security forum: Donald Trump and Hillary Clinton participated in a televised national security forum Wednesday with "Today" show host Matt Lauer as moderator and members of the audience asking questions. Clinton was asked by a former fighter pilot why he should trust her in the wake of her ongoing troubles with transmitting classified information. Trump praised Vladimir Putin, saying the Russian president was a better leader that Barack Obama.

2. Russian jet: A Russian jet fighter came within 10 feet of a U.S. Navy reconnaissance plane near the Black Sea Wednesday, in an encounter American military officials called "unsafe and unprofessional." The Russian fighter at first maintained a 30-foot distance from the U.S. Navy P-8A aircraft, but eventually flew closer to the plane in the 19-minute encounter.

3. Lochte suspension: Swimmer Ryan Lochte, who exaggerated claims of being robbed while competing in the Summer Olympics in Brazil last month, has received a 10-month suspension from competition, and will not be allowed to participate in the 2017 world championship meet. The three other swimmers involved in the incident will reportedly be suspended from competition, too, but not for as long as Lochte.

4. 9/11 flag: The flag that was hoisted above the smoldering rubble of the World Trade Center towers after the attack on Sept. 11, 2001, will be placed in the 9/11 Museum in New York City Thursday. The flag  that went missing after the ionic photo of firefighters raising it at Ground Zero was shot, was found in Washington State in 2014. It's owner donated it to the museum.

5. Exercise and alcohol: A new study is showing evidence  that exercising may "cancel out" the effect alcohol has on cancer deaths brought on by drinking. The study appears to show that exercise also lessens the risk of dying from any disease in which alcohol plays a part.
