President Barack Obama says legislation to keep transportation projects going and prevent interest rates from doubling on new loans to college students will help many in this country.

But he says "we've got more to do."

Obama said in his weekly radio and Internet address Saturday that the measure he signed into law Friday will keep thousands of construction workers on the job and help students and their families.

But he said Congress should do more to promote infrastructure and reform and expand financial aid offered to students.

In the Republican address, Rep. Ann Marie Buerkle of New York said Obama's policies are "making things worse, starting with his health care law."

She said the Supreme Court's upholding of the law adds urgency to repealing the health care overhaul.
