Lobbying is fierce on both sides as the Senate Commerce Committee prepares to markup an extension of the internet tax moratorium extension. With the support of Ranking Member Ted Stevens, Chairman Inouye will take up the Carper-Alexander proposal, which will extend the ban through 2011. The Administration weighed in yesterday with a letter from Commerce Secretary Gutierrez and Treasury Secretary Paulson supporting the competing Wyden proposal, which would extend the moratorium permanently. The markup is scheduled for 2:30 p.m.
