Lamar Smith (R-Texas), the House Judiciary Committee chairman, told The Wall Street Journal on Wednesday that the bill has already accommodated objections by the opposition.
"It's easy to engage in fear-mongering and it's easy to raise straw men and red herrings, but if they read the bill they will be reassured," Smith told the WSJ.
Smith also dismissed charges that the bill amounts to censorship.
"Obviously there's no censorship in the bill and no one can indicate any censorship whatsoever. It's not censorship to want to stop illegal activity," Smith told the publication. "That's all we do. We're trying to impede illegal activity by foreign websites."
Smith was apparently unmoved by a widespread Internet blackout on Wednesday protesting SOPA. Meanwhile, PIPA remains scheduled for a vote in the Senate on Jan. 24.
