Here's a roundup of news trending across the nation and world today.

What to know now:

1. Ben Carson on Oregon shooting: Ben Carson is answering questions about his stance on  gun control  following comments Monday on a Facebook question-and-answer  session. The retired  neurosurgeon  who is seeking the GOP nomination  for president argued that the  right to own a gun tops any consequence of using the weapon. "I never saw a body with bullet holes that was more devastating than taking the right to arm ourselves away," Carson wrote.  He told  Fox News on Tuesday that he would have rushed the gunman had  he been  in  a situation like the one at  an Oregon  college last week, and  wouldn't "just stand there and let him shoot me."

2. Bill Clinton on Donald Trump: Former President Bill Clinton told Stephen Colbert on "The Late Show" Tuesday that he believes  the success of Donald Trump's run for the GOP nomination has come  because  he is the "most interesting character out there." During his appearance, Clinton joked about his  wife's appearance on "Saturday  Night Live" this past weekend,  and denied that he counseled  Trump to get into the race for president.

Speculation over who told New York Times columnist Maureen Dowd that Biden could be considering a run for president in 2016 had run rampant since Dowd's column was published in August.

4.  Thousands of inmates set for release: The Justice Department announced  they  will  be releasing some 6,000 federal inmates from prison this fall. The early release is an effort to reduce overcrowding and address harsh sentences ordered for minor drug offenses, Justice Department officials said.  An Associated Press review of a portion of the cases showed that  some of those to  be released were charged with "carrying semi-automatic weapons, had past convictions for crimes including robbery and assault, moved cocaine shipments across states and participated in international heroin smuggling."

5. Model sues Cosby: A woman who says she was sexually assaulted by Bill Cosby has filed suit  against the comedian. Chloe Goins' lawsuit filed in U.S. District Court in Los Angeles claims she was drugged and  assaulted  by Cosby at the Playboy Mansion in 2o08. She is seeking punitive damages.
