John Thompson, outgoing chief executive of security company Symantec, is being considered for the post of secretary of the U.S. Department of Commerce, according to a news wire report on Tuesday.

"He (Thompson) is the leading candidate," Reuters quoted an unidentified senior Democratic source as saying. "He is still being vetted."

Thompson, who announced in November that he would step down in April, held several fund-raisers for Obama at his Silicon Valley home.

"John has always kept his political activities personal in nature and separate from him activities as head of Symantec," a Symantec spokesman said in an e-mail. "He hasn't commented in the past and hasn't been making himself available this time around, either."
