PHILADELPHIA, Pennsylvania (CNN) – Sen. Barack Obama said Tuesday he chose to run for president because he believes "we cannot solve the challenges of our time unless we solve them together."
Speaking to supporters at Philadelphia's National Constitution Center, the Democratic presidential candidate said he rejected racially charged comments made by the Rev. Jeremiah Wright, but explained the root of his remarks.
Wright used to preach at the Trinity United Church of Christ, where Obama worships.
Obama said that his belief that all people want to move in the same direction comes from his "unyielding faith in the decency and generosity of the American people. But it also comes from my own American story."
well delivered speech Sen Obama.
Sir, my Constitution is not "stained"!!!!! How dare you???
ACTIONS (sitting in a racist hate-filled church and then denying that you ever heard the controversial speeches) speak LOUDER than YOUR WORDS
Obama is not viable. Period.
Which of Obama's "truths" do we believe? The one last week where he said he was never present and never heard his pastor's inflammatory remarks or the one today where he said: "Did I ever hear him make remarks that could be considered controversial while I sat in church? Yes...."
so now im supposed to feel bad for the guy because he is an African American.
essentially he wants affirmative action for the presidency – he wants people to feel bad for him
OBAMA IS NOT FIT TO BE PRESIDENT!
Oblahma! We are tired of the speeches and empty rhetoric. We want Sen. Clinton! It's not too late. We already have buyer's remorse and luckily we can do something about it now!
It's not your race that scares me Obama, it's your tax and spend budget ideas. Big government is not the answer to us all getting along..
Good speech. If only he would have included a segment addressing the Latino community, it would have been a great speech. At least, he's going to have people discussing the race issue without having to be defensive.
Now that is the president I want. Someone who will not ignore the underlying issues bu covering it up with a lot of political banter and who is willing to take a risk to address one of the most controversial issues of our society. Tell it as it is OBAMA!!!!!! YES WE CAN!!!
All I can say is EXCELLENT... I don't care who you vote for, all the candidates are good this year... but everything he said, needed to be said...
Wow. This is easily the most meaningful speech on race since Dr. King's "I had a dream." If Obama can deliver as a President as he did today... we're in for something special. If you haven't watched it, go find it and do
Oblahma! We are tired of the speeches and empty rhetoric. We want Sen. Clinton! It's not too late. We already have buyer's remorse and luckily we can do something about it now! Hillary for President !
hi. i'm barack obama and i have a message of hope (and deceit)!
The best speech I have ever heard.
Obama need to stop using racism as the weapon against the other people who are critiquing his campaign. This is the real problem that he is facing.
As a white American, thank you for bringing ua all into the open and making race and the need for racial healing an okay subject to us all. It is now up to all Americans to try to understand each other. This understanding will make us A STRONGER AMERICA!!!!!!!!!!!
YOU JUST HIT THE BALL OUT OF THE PARK!!!

This speech was an important one and perhaps historic one. Obama showed leadership and honesty that is rare in politicians today.
This is my president. This speech hit me very hard. I can't explain it.
When does Hillary get equal free airtime? This speech was nothing more than political rhetoric.
A good speech, who wrote for him?
the same time, we need the press conference too.
obama's speech was one of the most powerful speeches i have ever heard. it moved me beyond words. i hope people now realize that he doesn't believe in what Wright has been saying in the clips that have been floating. Obama is the only candidate that can bring people together and solve the problems of America. i have supported him from day one and will continue to support him on his path to becoming the next president of the U.S.!!!!!!
Wolf, why did you have such a sorry face after the speech of Obama?
Sorry, your Hillary does not have such intellectual depth regarding history, society and vision.
I am interested to hear how ppl will take this. I thought he addressed the issue, which is what ppl called for and now he has elevated himself to another platue. He is a great man. I am PROUD to be a Barrack supporter.
This was a great time in our immediate history that gives one a since of self and pride.
Action speakslouder than words. Obama's candidacy is finished. If Democrates want to win, they should all get behind Hillary Clinton otherwise there will be President John McCain in January 2009.
