Texas Gov. Rick Perry (R) says that it's just a coincidence that he and eight other lawmakers received donations of $5,000 each from Merck lobbyists just a few days before mandating the drug giant's HPV cervical cancer vaccine for all females in Texas ages 12 and up.

"There's been a lot of pressure about the implications of vaccinating young girls against sexually-transmitted diseases," says CNN's Ali Velshi in the video below, "some people thinking that that encourages promiscuity at that age."

He reports though that "this thing is coming undone by word, rumor and report of connection between Rick Perry's office and Merck."

The main lobbyist for Merck previously worked as Chief of Staff for Gov. Rick Perry. Several other states are considering making the vaccine mandatory, thanks in part to Merck's aaggressive lobbying.
