“He has proven himself to be an up-and-coming leader who is always willing to reach across party lines,” Baucus said.
Baucus also praised Brown, who won a second six-year term in November, as "a fierce advocate for of the middle class."
Brown, who has opposed trade deals over concerns that they would force companies to ship jobs overseas, backed a bill last week to grant permanent normal trade relations (PNTR) with Russia. He argued that the bill included improvements over other PNTR deals and that it will help U.S. exporters.
“My biggest priority is to help build the middle class, and this committee provides a great opportunity to do so: from ensuring a fair tax code, to standing up for Ohio's manufacturers and workers when it comes to foreign trade, to protecting Social Security and Medicare,” Brown said.
