President Obama dismissed those who have expressed skepticism that the nation's healthcare system will be overhauled by Congress this year, saying "yes we can" revise it. In an appearance in the Diplomatic Reception Room of the White House, Obama praised an agreement reached by drug companies to help close a cap in Medicare's prescription drug coverage. He said the pharmaceutical industry's pledge to spend $80 billion over the next decade to reduce the cost of drugs would pay for a portion of his healthcare plan.
