Media find more troubling factors in McCain's past

The McCain-Palin announcement that they are "taking the gloves off" in going after Barack Obama's character has resulted in more investigations into John McCain's past associations and activities. In the latest, MSNBC is running this story about McCain's connection with a group involved in the Iran-Contra business in the 1980s.

WASHINGTON - GOP presidential nominee John McCain has past connections to a private group that supplied aid to guerrillas seeking to overthrow the leftist government of Nicaragua in the Iran-Contra affair.

McCain's ties are facing renewed scrutiny after his campaign criticized Barack Obama for his link to a former radical who engaged in violent acts 40 years ago.
