WASHINGTON - Illegal immigration into the United States would decrease by only 25 per cent under a far-reaching Senate immigration bill, according to an analysis by the Congressional Budget Office that also finds the measure reduces federal deficits by billions. Supporters of the legislation moving toward a vote on the Senate floor seized on the deficit-reduction findings by Congress' nonpartisan scorekeeping agency, along with the agency's forecast that the immigration measure would boost economic growth as millions of workers join the workforce and begin to pay taxes.

President Barack Obama said Russian and US nuclear weapons should be slashed by up to a third in a keynote speech in front of Berlin's iconic Brandenburg Gate in which he called for a world of "peace and justice". Obama used the once divided city's rebirth as a metaphor for progress, as he stood on the east side of the route of the Berlin Wall, and warned the "complacent" West that history did not stop with its Cold War victory.

In 2008, Barack Obama wowed a euphoric 200,000-strong crowd in Berlin as the self-appointed embodiment of the power of politics to ignite change. On Wednesday, after more than four tough years in power, he will stand up in Berlin again, as a testament to the difficulty of remoulding domestic and global political forces that combine to frustrate change. In Berlin five years ago, candidate Obama defined eight foreign policy goals that would motivate his subsequent administration, arguing that the world faced a unique moment of "possibility."

By Susan Heavey WASHINGTON (Reuters) - Former U.S. Secretary of State Hillary Clinton has not committed to a run for president in 2016 but on Tuesday she picked up an endorsement from Missouri Senator Claire McCaskill, who announced she is supporting a group encouraging Clinton to run for the White House again. McCaskill, who in 2008 backed Barack Obama over Clinton in the Democratic primaries, became the first member of Congress to announce her support for Clinton.
