5 things you need to know Friday

1. Suspect in Charleston shooting to make court appearance

Dylann Storm Roof, the man who allegedly shot and killed nine people in a South Carolina church, is expected to appear in court Friday afternoon for a bond hearing, according to media reports. Roof, 21, is suspected of killing six women and three men inside of the Emanuel African Methodist Episcopal Church in Charleston, S.C. He was captured Thursday in Shelby, N.C., 14 hours after the rampage. Details of Roof's life have started to emerge, including arrests earlier this year for trespassing and a misdemeanor drug charge. Meanwhile, the people of Charleston continue to mourn the victims and groups around the country plan to remember the people who died during their annual Juneteenth celebrations.

2. Brian Williams speaks out to Matt Lauer

NBC News' prodigal son returns. Brian Williams, the former host of NBC Nightly News, will make his first public remarks about his suspension in an interview with NBC's Today show co-host Matt Lauer. The pre-recorded interview will air Friday morning on the Today show and Friday evening on NBC Nightly News. NBC also announced that Lester Holt will take over as permanent anchor at NBC Nightly News, and that Williams will return to MSNBC as a breaking news anchor — a move that media columnist Rem Rieder calls "a truly terrible decision."
