They are new, enthusiastic and changing the environment on Capitol Hill.

House Agriculture Committee Chairman Frank Lucas says "do not underestimate the effect" of the large number of freshmen lawmakers on his committee, which will sit down to overhaul U.S. farm subsidies next year. USA/

"This session of Congress is a little different from the ones I've participated in previously. A huge number of new members," Lucas said at a Reuters Global Food and Agriculture Summit. "I've got a very enthusiastic bunch of new faces."

It turns out that half of the House Agriculture Committee is new -- 16 of 26 Republicans and 7 of 20 Democrats.

"Now, granted, freshmen Democrats are hard to come by," he said, not missing a beat in taking a swipe at Democrats who were pounded in the November elections and lost control of the House of Representatives to Republicans.

"So literally 23 of the 46 members of the committee -- no committee experience, no Farm Bill experience. It's a slightly different dynamic as we go through the course of this year and next year," Lucas said.
