Immigration protests hit Nats stadium

Protesters opposed to Arizona's immigration crackdown law took action at Nationals Park in Washington, D.C., on Sunday during a game between the Arizona Diamondbacks and Washington Nationals.

About three dozen protesters picketed outside the stadium and four were apprehended by security after they stormed the field during the fifth inning of the game. At the same time, several people seated in center field seats unfurled a banner that read "Bud Selig Move All Star Game No SB 1070."

Protest groups have demonstrated at several baseball stadiums around the country in an effort to convince Major League Baseball Commissioner Bud Selig to move the 2011 All-Star Game from Arizona's Chase Field to punish the state for passing the law, which they say will lead to racial discrimination against Latinos. 

Selig has declined to comment on the issue, even though the players union has said it is unhappy with it. A federal judge enjoined some of the most controversial parts of the law.

The Arizona law has also touched off a searing political debate over immigration reform heading into the midterm elections. Last week, President Obama signed into law $600 million in border-security funding and urged both parties to support comprehensive immigration reform.

Republicans applauded the move but said more needs to be done before they agree to negotiate.

The baseball efforts have earned the support of several Democrats in Congress.
