Even though Barbara Walters is talking about her affair, and Oprah Winfrey is asking questions, that doesn't mean everyone is willing to talk. In fact former U.S. Sen. Edward Brooke, who Walters said she had an affair with in the 1970s, has declined to comment.

According to the Associated Press, Brooke, 88, said during a phone interview from Miami, "I have had a lifetime policy and practice of not discussing my personal and private life, or the personal and private lives of others, with the notable exception of what I wrote in my recently published autobiography, `Bridging the Divide: My Life.'"

Brooke does not mention having a relationship with Walters in his book. His memoir was published in 2006.

In Walter's appearance on "The Oprah Winfrey Show," which is scheduled to air Tuesday, she shares details of her relationship with the married Brooke that lasted several years in the 1970s, according to excerpts of the show provided to the AP.

While on the Oprah show, the talk show host asked Walters if she was in love with Brooke during the affair.

Walters responded by saying, "I was certainly - I don't know - I was certainly infatuated."
