From NBC's Andrea Mitchell

Democratic sources say California Rep. Xavier Becerra (D) is in Chicago today to meet with President-elect Obama.

We have confirmed that they are meeting to discuss a possible appointment as US Trade representative.

Becerra voted for NAFTA in 1993, a vote he later said he regretted because of the lack of labor protections.

He also supported China's World Trade Organization membership in 2000, and last year he pushed for passage of the trade deal with Peru, after labor protections were added. 

In the past, he also has opposed trade deals -- like the Central American Free Trade Pact.

A member of the House Ways and Means Committee (which oversees trade), Becerra is the son of immigrants and holds undergraduate and law degreed from Stanford University.

If nominated, he would be the second high-ranking Hispanic appointment by Obama -- after yesterday's nomination of Bill Richardson to be Commerce secretary.
