Jaitley was here to brief media about achievements of the NDA government in the last one year.
Asked about Baijal's allegations, the senior BJP leader said, "He worked with me also, I found him to be a bright and outstanding officer.
"He has been unfairly targeted by UPA. He was targeted and harassed. He met me after retirement and I was aware about the harassment inflicted upon him," Jaitley said.
In his self-published book, "The Complete Story of Indian Reforms: 2G, Power and Private Enterprise - A Practitioner's Diary', Baijal, who was appointed head of the telecom watchdog by the NDA government in 2003, said the 2G scam trail began under UPA's Telecom Minister Dayanidhi Maran.
