While she said it is former Vice President Dick Cheney's right to challenge the Obama administration, former first lady Laura Bush said her husband, former President George Bush, believes he "owes President Obama his silence on issues, and that there's no reason to second-guess any decisions that he makes."

"I think [Cheney] feels obligated. You know, these are issues that are really important to him, and he knows a lot about them," Bush told "Good Morning America" today in an exclusive interview from the former first family's Dallas home, referring to Cheney's recent criticisms of the current administration's national security policies. "So you know, I understand why he wants to speak out."
