President Barack Obama's push to transform the country's health care system is picking up steam.  A major announcement is set to come from the U.S. House of Representatives on Tuesday.

The House is set to release a massive healthcare overhaul bill and it has many members grumbling about costs.  But lawmakers also have an ultimatum from the president.

"I just want to put everybody on notice, because there was a lot of chatter during the week that I was gone.  We are going to get this done," Obama declared.
    
The president has also enlisted some new blood in the health care battle, naming his choice for the post of Surgeon General at the White House on Monday.  Dr. Regina Benjamin is the founder and operator of a rural health clinic in Alabama.
   
Obama made it clear while making Benjamin's announcement that he is focused on his mission to transform health care. 

"For those naysayers and cynics who think that this is not going to happen, don't bet against us," he said.
    
The president's strong words came amid growing concerns in Congress about exactly how the country is going to pay for universal health care.
    
By some estimates, the measure could cost $1 trillion over 10 years, and the clock is also ticking on the president's original timeline.

"I am confident that both the House and the Senate are going to produce a bill before the August recess," Obama said.

Speaker of the House Nancy Pelosi, D-Calif., agreed with the president's timeline and thinks a House vote could come by August.  She said Tuesday's initiative is not the final bill, but a version that could still be shaped as it goes through the committee process.   
    
However, over in the Senate, even the early stages of the healthcare reform bill has yet to be seen.
