Transit group: Ryan's budget 'misguided'

Millar said public transportation cuts are ill-advised at a time of high gas prices.

"With gas prices rising steadily, now is not the time to place misguided restrictions on public transportation and high-speed and intercity passenger rail investment," Millar said. "Public transit is the quickest way for people to beat high gas prices if it is available.”

Ryan has repeatedly said not doing anything about the growing federal deficit would be irresponsible. His budget plan would cut $5.8 trillion in government spending over 10 years.

"I would say that what is draconian is doing nothing and lying to the American people about these fiscal problems that we have," he said in a January interview with ABC News's Diane Sawyer.
