Schwarzenegger, Shriver's kids speak out

Arnold Schwarzenegger and Maria Shriver's children have taken to Twitter, offering a bit of insight into the struggle the family is enduring following the bombshell revelation that Schwarzenegger fathered the child of a household staffer.

The couple's 17-year-old-son, Patrick tweeted, "Some days you want to quit and just be normal for a bit, yet I love my family till death do us apart." He signed it Patrick Shriver.

Patrick's 21-year-old sister, Katherine, tweeted, "This is definitely not easy but I appreciate your love and support as I begin to heal and move forward."

CBS News Correspondent Ben Tracy says the words come as published reports indicate Schwarzenegger may have fathered the boy 14 years ago, approximately the same time Shriver was pregnant with their youngest son, Christopher.

Back in 2003, had Schwarzenegger's secret gone public, it could have derailed his run for governor, Tracy points out. However, after allegations of womanizing, it was Shriver who stood up for him, saying, "He's an extraordinary father. He's an extraordinary husband."

Psychotherapist David Swanson says of Shriver today, "You've gone on record saying you would vouch for his character, he was that good of a man, and yet everything you believed in, your marriage, the character of your husband, it all falls down around you. If that's not the worst sense of betrayal, I don't know what is."

Shriver now seems to be walking away. She has reportedly known about her husband's secret child since January. That's when she moved out of the couple's Los Angeles mansion.

But headlines following Schwarzenegger's admission forced her to break her silence. In a statement Shriver says, "This is a painful and heartbreaking time. As a mother, my concern is for the children. I ask for compassion, respect and privacy as my children and I try to rebuild our lives and heal."

Tracy said on "The Early Show" it remains to be seen if all this will affect Schwarzenegger's attempt to relaunch his movie career.
