The Republican National Convention is turning its attention to domestic themes one day after lauding President Bush's leadership in the global war on terrorism.

California Governor and well-known actor Arnold Schwarzenegger takes to the podium at Madison Square Garden as Republicans highlight the theme: People of Compassion.

Mr. Schwarzenegger, who entered elected office for the first time last year by winning California's gubernatorial recall election, has championed the Special Olympics program for disabled people and been a consistent advocate for fitness. He is expected to speak about his personal journey as an Austrian immigrant who achieved fame and fortune in the United States and rose to lead America's most populous state.

Also addressing delegates will be First Lady Laura Bush, a former librarian who has worked to promote literacy and education in the United States. Speaking on ABC's Good Morning America television program, Ms. Bush said she will give her own perspective on why her husband deserves another term in office.

"I think he has the character and the integrity and the resolve to be president during these very difficult times," said Ms. Bush. I want to talk about the personal moments, the times that I have seen him when other people have not seen him, as we face these difficult challenges."

Monday, the convention featured a tribute to the victims and heroes of the 9/11 terrorist attacks on the United States.

Arizona Senator John McCain was one of many speakers who defended President Bush's handling of the war on terrorism, including the decision to invade Iraq last year.

"Our choice was not between a benign status quo and the bloodshed of war," said Mr. McCain. "It was between war and a graver threat. Do not let anyone tell you otherwise."

Former New York Mayor Rudy Giuliani also praised Mr. Bush for the way in which he responded to the city's needs after 9/11.
