Here is a look at some of the stories that CNN plans on covering this week:
Martin Luther King Jr. documents go online
Monday is Martin Luther King Jr. Day, one of 10 national holidays in the United States.
Besides marking the day as a federal holiday for the 26th time, January 16, 2012, begins a new age of online accessibility for those wanting to know more about King and his work.
The King Center Imaging Project, which makes 200,000 of the civil rights leader's documents quickly accessible online, goes live Monday. King's "I Have a Dream" speech, his Nobel Peace Prize acceptance speech and his letter from a Birmingham, Alabama, jail are among the documents available.
The Martin Luther King Jr. Center for Non-violent Social Change in Atlanta and JPMorgan Chase & Co., working in partnership with AT&T Business Solutions and EMC, are responsible for the project.

Taking King at his words
The memorial to Martin Luther King Jr. has sparked controversy, and perhaps this is fitting. He was a controversial man whose humanity - and words - still speak volumes today.
There's nothing better than politicians who are secure enough to make fun of themselves, especially this winter when tensions are high among the Republican presidential candidates. "The Late Show with David Letterman" seems to be a popular place to let the rest of the country know that they don't take themselves too seriously.
'It's a hairpiece' - Monday night, Mitt Romney visited Letterman to share the top ten things "he'd like to say with the American people."
Brain freeze - In November, Rick Perry stopped by "The Late Show" to share his top ten excuses for his now-infamous brain freeze.
The 9-9-9 plan - Before Herman Cain suspended his presidential campaign, he took advice from Letterman on his 9-9-9 plan.
GOP presidential hopeful Herman Cain won't decide whether to stay in the race until after he speaks with his wife in person, he told reporters.
After being on the road campaigning during a week that a woman came forward with allegations of a 13-year affair with Cain, which he denies, the embattled candidate said he will return home Friday and have the chance to talk in person with his wife Gloria.
"I haven't had an opportunity to sit down with her and walk through this with my wife and my family," Cain said Wednesday night in Ohio. "I will do that when I get back home on Friday."
He will also re-evaluate his support and the impact that this latest allegation has had on his fund raising, Cain said.
While Cain said he has spoken with Gloria Cain about the allegations many times since Monday by phone and had "lengthy conversations," he said he will not "make a decision until after we talk face to face."
FULL STORYA third woman will make false sexual accusations against Herman Cain, the GOP presidential candidate told CNN Monday.
Cain told CNN's "Situation Room" that the woman will allege that she has had an affair with him.
"This individual is going to accuse me of an affair for an extended period of time," Cain said. "It is someone that I know who is an acquaintance that I thought was a friend."
Cain said he learned about the accusation after his lawyer talked to a reporter about the accusation.

Today's programming highlights...
10:00 am ET - Herman Cain in Michigan - GOP presidential candidate Herman Cain is looking to move on from the sexual harassment scandal that has dogged his campaign. He speaks to voters in Ypsilanti, Michigan.
A Chicago woman said Monday that Herman Cain sexually groped her in 1997 when Cain was head of the National Restaurant Association.
Sharon Bialek made the claims during a press conference with famed defense attorney Gloria Allred. Bialek is the fourth accuser to come forward with allegations of inappropriate behavior by Cain.
Cain has vehemently denied committing sexual harassment.
Full story at CNN Politics[Updated at 6:24 p.m. ET] Texas Gov. Rick Perry told CNN on Thursday that there was "no apology needed" from his Republican presidential campaign to fellow GOP challenger Herman Cain, who claims Perry's campaign is responsible for what Cain calls "baseless" sexual harassment allegations against him.
"Our campaign didn't have anything to do with it," said Perry, adding he'd fire any staffer if he found out they were "passing on rumors."
[Updated at 4:55 p.m. ET] GOP presidential candidate Herman Cain denounced a claim by an Oklahoma Republican political consultant that he'd seen Cain demonstrate inappropriate conduct toward a female employee during Cain's tenure as head of the National Restaurant Association.
"This is absolutely not true," Cain told Sean Hannity on the Hannity's syndicated radio program, regarding the account that Chris Wilson made on CNN and elsewhere. "They can't prove anything ... I think this Chris Wilson guy is just trying to help out the (Texas Gov. Rick) Perry campaign."
The Perry campaign has claimed it didn't know about the allegations. Wilson is currently doing polling for a political action committee supporting Perry's bid, but the group is independent of the campaign and by law cannot coordinate with it.
Allegations that Cain engaged in sexual harassment in his past surfaced Sunday.
Cain on Thursday continued to deny the allegations and said he won't be deterred by the controversy that has dominated his front-running campaign for the Republican presidential nomination.
[Initial post, 4 p.m. ET] Republican presidential contender Herman Cain has raised $1.2 million since allegations of sexual harassment in his past surfaced Sunday, his campaign said Thursday.
