Millions of immigrant workers are expected to boycott work and school today in support of nationwide May Day protests against anti-immigrant legislation being considered in Washington. Dubbed “A Day Without Immigrants” protests are planned in over 70 cities with the largest demonstrations expected in Los Angeles and Chicago. Immigrant rights groups are calling on immigrant workers to not show up for work and to not buy anything all day. Thousands of stores and businesses are closed for the day. In Los Angeles, port truckers are calling for a general strike and a shutdown of the area’s ports. Organizers in Los Angeles are predicting mass student walkouts. Tyson Foods, the world’s largest meat producer, has shut down nine of its 15 plants. We’ll have more on the boycott in a few minutes.

Today’s protests comes on the heels of a weekend that saw a pair of major demonstrations. On Saturday, Cindy Sheehan, Jesse Jackson and Susan Sarandon led a large anti-march rally in New York. Organizers said 350,000 people took part. Then on Sunday, tens of thousands gathered in Washington to call for an end to the genocide in the Darfur region of Sudan. It was this country’s largest demonstration against the genocide to date. The protest came as Sudan inches forward on a peace deal. A deadline to reach a deal was originally set for Sunday but it was extended by 48 hours.
