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

1. Travel ban begins: Despite some back and forth over the definition of a "bona fide" relationship, President Donald Trump's revised travel ban went into effect Thursday night. Those from six predominately Muslim nations wishing to immigrate to the United States and any refugee coming into the United States must have a "close family" or school or business tie to enter the country. Refugees must already have a visa, as the document required to enter the United States will not be granted for the next 120 days. Late Thursday, the state of Hawaii filed a court challenge to the administration's definition of what a close U.S. relationship means.
2. Venus Williams caused accident: Tennis star Venus Williams was at fault in a car crash that resulted in the death of a man in Palm Beach Gardens, Florida, according to police there. Witnesses say Williams ran a red light and then was hit by a car driven by Linda Barson. Barson said she entered the intersection on the green light and could not stop before hitting Williams as she came into the intersection. Barson's husband, Jerome was critically injured in the wreck and died two weeks after the June 9 accident. No charges have been filed in the incident.
