SAN ANTONIO -

With the Obama health care system still lagging behind needed numbers, some San Antonio leaders turned out Saturday to give it a push.

The mayor, his congressman brother, and other members of Congress led the effort to put some political muscle behind the president's troubled health care program.

They spoke at a large event aimed at getting people informed and signed up for Obamacare.

Hundreds of people came to the event at San Antonio College to hear about the health care plan, or to sign up for the program.

Mayor Julian Castro and his brother congressman Joaquin Castro spoke about the benefits they say people on the plan will have.

Congressman Pete Gallego also spoke, and acknowledged there have been problems with the system's start.

But Gallego said people need to hear about the president's program - the good and the bad - so they can make better choices about their health care.

Gallego said it's been clear there are problems with the health care plan, but sessions like the one Saturday can help people be better informed about what needs to change and what needs to stay.

The deadline to sign up for Obamacare is March 31.

People not signed on to a health care plan by that date could incur tax penalties.
