In a prime-time press conference broadcast live across the United States, President Barack Obama has been reflecting on his first 100 days in office.From the onset, his agenda has been jam-packed, dealing with Iraq, Afghanistan, the economic crisis and now swine flu among other issues. The president promised to keep up the whirlwind pace. “I think we are off to a good start but it is just a start,” he told the White House news conference. “I am proud of what we have achieved but I am not content. You can expect an unrelenting, unyielding effort from this administration to strengthen our prosperity and our security – in the second hundred days and the third hundred days and all the days after that.” The milestone was marked by a big victory for the President in the Democratic-controlled Congress. Despite no Republican support, it approved a compromise budget plan for 2010, in a move Obama says will help heal the US economy.
