JUDY WOODRUFF:

And back in this country, newly elected Montana Congressman Greg Gianforte will not go to jail after all for assaulting a reporter. The Republican pleaded guilty today to a misdemeanor charge, and was sentenced to 40 hours of community service. He will also attend 20 hours of anger management counseling and pay a fine of $385.

A Pennsylvania jury has begun deliberating in Bill Cosby's sexual assault trial. The defense rested abruptly today. Cosby himself, accompanied by his wife for the first time, declined to testify. His defense team argued the comedian and his accuser had a consensual relationship. Prosecutors argued that Cosby drugged the woman.

In Orlando, Florida, today, they remembered the deadliest mass shooting in modern U.S. history. A gunman, Omar Mateen, killed 49 people at a gay nightclub last June 12, before police killed him. He'd pledged allegiance to the Islamic State group. This morning, a vigil began at 2:00 a.m., the same hour as the rampage. Names of the victims were read aloud, and hundreds carried candles and laid flowers.

BUDDY DYER, Mayor of Orlando, Florida: We are not here to relive the horror of that day. We're here for a greater purpose. We're here to remember the innocent lives that were lost. We're here to honor them.

Orlando has been anointed to show the world how to combat hatred and evil and promote quality and embrace diversity. And we don't just have the opportunity to do this. We now have the responsibility to do this.
