By Richard Valdmanis BOSTON (Reuters) - The older brother of Boston Marathon bomber Dzhokhar Tsarnaev changed from a roisterous boxer known for flashy outfits into someone with a bushy beard and drab clothes and obsessed by Islam, following a trip to Russia in 2012, witnesses said on Tuesday. The testimony before a federal jury in Boston comes as lawyers for Tsarnaev build their argument that the 21-year-old ethnic Chechen was a pawn in his now-dead brother's scheme to bomb the race on April 15, 2013, and should be sentenced to life in prison, not death. Tsarnaev was convicted this month of killing three people and injuring 264 in the bombing, and shooting dead a police officer three days later alongside the older brother, Tamerlan, a 2009 New England boxing champion. Rogerio Franca, who lived near the Tsarnaevs in Cambridge, Massachusetts, told jurors Tamerlan was a partier before his trip to Russia, but transformed into someone more closely resembling a devout Muslim when he returned.

By Amanda Becker WASHINGTON (Reuters) - The leader of the largest federation of U.S. labor unions has called on Hillary Clinton and other presidential hopefuls to oppose an Obama administration trade pact. AFL-CIO President Richard Trumka on Tuesday delivered his first address about the U.S. presidential election in November 2016, laying out criteria the federation's 56 member unions will use to assess candidates. "The TPP is the latest example of a long-term approach to trade that ... was designed to drive wages down, create special rights for corporations and export jobs," Trumka said, citing as another example a North America pact ratified under former President Bill Clinton in the 1990s. "There is no middle ground." Hillary Clinton, a former secretary of state, U.S. senator, first lady and the only Democrat who is formally campaigning for president, is considered the strong front runner for the party's nomination.
