After spending just over a week in Congress, freshman Rep. Anh "Joseph" Cao (R-La.) took on conservative radio host Michael Savage over the topic of immigration.

Responding to comments by Savage arguing immigrants have difficulty assimilating, which then leads them to become "gang-bangers," Cao said he hoped the Republican Party would reject such sentiments.

"A statement like that would be very anti-immigrant, almost to me borderlining to almost being racist, if you ask me," Cao told the liberal blog Think Progress. "So I hope that the GOP will not tolerate those kinds of views and will not take those positions."

Cao, the first Vietnamese-American elected to Congress, is an immigrant from that country.
