Immigration Marchers
A marcher carries a Mexico flag as protesters brave the cold and snow as they march from the Capitol to a park in Denver on Wednesday, May 1, 2013. About 200 people gathered at the Capitol for immigration reform. The May Day rallies carry a special sense of urgency this year, two weeks after a bipartisan group of senators introduced a bill that would bring many of the estimated 11 million living in the U.S. illegally out of the shadows. Colorado's rally comes just after the governor signed a bill allowing students in the country illegally to pay in-state tuition at state colleges and universities, ending a 10-year political battle.(AP Photo/Ed Andrieski)

Spain Financial Crisis
A woman walks past the Cibeles statue which bears a flag from Spain's second republic that somebody placed during a march in Madrid, Spain Wednesday May 1, 2013. Spaniards enraged by austerity, recession and sky-high unemployment are marching in some 80 cities in trade union-organized Labor Day rallies with large protests in Madrid, Barcelona and Bilbao. Spain's jobless rate is a record 27.2 percent, and 57 percent for those aged under 25. The government slashed its economic forecasts Friday, saying it would take two years longer than pledged to cut its swollen deficit; an acknowledgement that harsh austerity measures had failed to ease the financial crisis.
