WASHINGTON (CNN) - President Barack Obama will call his first 100 days in office "a good start," but say there's more work to be done in a speech commemorating the early milestone that has been used to assess presidencies since Franklin Roosevelt set out to tackle the Great Depression.
"[W]e are off to a good start, but it is just a start," Obama will say during the 8 p.m. speech, according to excepts released by the White House. "I am proud of what we have achieved, but I am not content. I am pleased with our progress, but I am not satisfied."
Obama's speech will come hours after Congress gave final approval to a $3.4 trillion budget that pays for many of his top spending priorities, including increases for health care, alternative energy and education.
He's expected to say that the budget begins laying "a new foundation" for the U.S. economy.
"It contains new investments in education that will equip our workers with the right skills and training, new investments in renewable energy that will create millions of jobs and new industries, new investments in health care that will cut costs for families and businesses and new savings that will bring down our deficit," he'll say, according to the excerpts.
Obama is also expected to cite the passage of his economic-stimulus plan, which included a tax cut the White House says will go to 95 percent of working families and a bill that ensures health care for 11 million children.
He credits his initiatives, including a banking-industry bailout intended to improve a badly battered housing market, with already saving or creating 150,000 jobs and making it possible for more people to refinance their homes - which he equates with another tax cut.
But, Obama says in the excerpts, challenges remain - from the swine flu outbreak and high jobless rates to projected long-term deficits and foreign threats including terrorism and nuclear proliferation.
"It is work that will take time. It will take effort," Obama says. "But the United States of America will see a better day. We will rebuild a stronger nation. And we will endure as a beacon for all those weary travelers beyond our shores who still dream that this is a place where all is possible."
