Cantor's office did not immediately respond to a request to comment on Issa's statement.
Although Smith has not responded directly to his fellow GOP chairman's comments, he promised on Saturday to push ahead with the legislation. His Judiciary Committee still needs to vote on the bill before it can reach the House floor.
Issa, who is a former chairman of the Consumer Electronics Association, is close with the tech community and has been an outspoken critic of SOPA. He had scheduled a hearing for Wednesday to examine the bill's potential negative consequences but canceled it after speaking with Cantor.
SOPA is designed to go after foreign websites that offer illegal copies of music, movies and TV shows with impunity. The bill would empower the Justice Department and copyright holders to demand that search engines delete links to sites “dedicated” to copyright infringement. Ad networks and payment processors would be prohibited from doing business with the sites.
