The Rev. Jeremiah Wright, former pastor for President Barack Obama, has said that the president "threw him under the bus" in a bid for election.

"No one in the Obama administration will respond to me, listen to me, talk to me or read anything that I write to them. I am 'toxic' in terms of the Obama administration," Write wrote in a letter to the president of Africa 6000 International earlier this year, obtained by the Associated Press.

"I am 'radioactive,' Sir. When Obama threw me under the bus, he threw me under the bus literally!" he continued. "Any advice that I offer is going to be taken as something to be avoided. Please understand that!"

Obama's relationship with Wright, who had officiated the president's marriage, was strained during the 2008 election campaign after videos revealing inflammatory remarks from the pastor went viral on the internet and garnered media attention.

Among the videos were clips of Wright saying that the United States brought on the 9/11 attacks due to its own "terrorism" overseas.

"We bombed Hiroshima, we bombed Nagasaki, and we nuked far more than the thousands in New York and the Pentagon, and we never batted an eye," Rev. Wright said in a sermon on Sept. 16, 2001.

Obama responded by saying that he thought Wright was "trying to be provocative" but added that he didn't consider "the pastor of his church in political terms," according to ABC News.

The final rift between Obama and Wright occurred after an April 2008 appearance by Wright at the National Press Club, where among other remarks, the pastor suggested that the AIDS virus was created by the U.S. government as a conspiracy against blacks, gave praise to controversial Islamic scholar Louis Farrakhan, and said that Obama secretly agreed with Wright while distancing him for political reasons.

Obama responded by saying he was "outraged" and "saddened" by the remarks and called the Wright's notions "ridiculous."

Such views "offend me. They rightly offend all Americans. They should be denounced," said Obama.

Obama left Wright's church, Trinity United Church of Christ in Chicago, Ill., shortly afterwards.

Wright had retired just months earlier as the official minister for the church, which is the largest congregation in the United Church of Christ denomination.
