"I know that many people are interested in my health," Yushchenko said. "During the last year, I've managed to get the majority of my energy back."
As for those responsible for the attack, Yushchenko believes they have found safe harbor in Russia. "Do you believe there is a connection to the Russian government?" Kerley asked. "I think I should not give any comments on this for the sake of the investigation," he said.
"It was a very, very difficult time for our entire family," said Ukraine's first lady Kateryna Yushchenko, a Ukrainian-American who was born in Chicago.
Also speaking exclusively to Kerley, Kateryna Yushchenko relived the harrowing ordeal. "There was a time when we went to a hospital where they told us that if we had not brought him, he would have died within nine hours."
She takes comfort in the fact that there had to be a higher purpose for what they were enduring.
"There must be a reason that we're going through what we are going through," she said. "He needed to survive to create the change in our country that is happening today. A very difficult path, but one that I think we are undergoing in a dignified and very positive manner."
