President Barack Obama and presumptive GOP nominee Mitt Romney want to continue low interest rates for student loans--as they argue whose policies will better help pay for higher education. If Congress does not act, interest rates will increase later this year.

Obama on Tuesday is visiting state schools to the battleground states of North Carolina and Colorado.

Romney's campaign is holding a conference call Tuesday morning on Obama's "failed economic policies on young adults" featuring the youthful Rep. Aaron Schock (R-Ill.) on a conference call.
