Here. Key passages:

I vehemently disagree and strongly condemn the statements that have been the subject of this controversy. ... Because these particular statements by Rev. Wright are so contrary to my own life and beliefs, a number of people have legitimately raised questions about the nature of my relationship with Rev. Wright and my membership in the church. ... The statements that Rev. Wright made that are the cause of this controversy were not statements I personally heard him preach while I sat in the pews of Trinity or heard him utter in private conversation. When these statements first came to my attention, it was at the beginning of my presidential campaign. I made it clear at the time that I strongly condemned his comments. But because Rev. Wright was on the verge of retirement, and because of my strong links to the Trinity faith community, where I married my wife and where my daughters were baptized, I did not think it appropriate to leave the church.
