Anderson Cooper 360

The AC360 Weekly Buzz: Whitney Houston, Mitt Romney, Syria, Haley Barbour, Valentine's Day

What everyone’s talking about:

The world lost a musical icon last Saturday when Whitney Houston, 48, was found dead in her suite at the Beverly Hilton. Her funeral will be televised this coming Saturday from her church in Newark, New Jersey. Anderson spoke to Houston’s pastor and friend, Marvin Winans, who’s coping with the loss; he’ll be delivering her eulogy. Earlier in the week, Houston’s close friend Kelly Price told Anderson that the singer was “happy, celebratory” when they performed together at a club two days before Houston’s death. Price said she saw her friend drinking champagne – although not excessively. But, a source said Houston was drinking heavily at the Beverly Hilton on two mornings last week; she ordered her drinks before 10 a.m. from the lobby bar and in the pool area. Houston’s cause of death has been “deferred”, as stated on her death certificate, but the prescription pills found in her hotel room are now the focus of the investigation. In light of the tragic news, Anderson spoke to HLN’s Dr. Drew and CNN’s Dr. Sanjay Gupta about the growing epidemic of dangerous prescription drug combinations, especially when used with alcohol.

Syrian President Bashar al-Assad announced a constitutional referendum on Wednesday, set to take place February 26. While his government hailed it as an important reform initiative, the city of Homs and other towns continued to be pummeled by shelling. On Thursday at least 70 people were killed, according to a Syrian activist group. CNN’s Arwa Damon spoke to Anderson on Wednesday from the embattled city of Homs. She witnessed the despair and violence described by the Syrian activists we’ve spoken to over the past couple weeks.

We’ve repeatedly asked former Mississippi Gov. Haley Barbour to come on our show to talk about the controversial pardons he gave to convicted murderers and criminals as he left office. He declined, so CNN’s Ed Lavandera tracked him down and tried to get some answers.
