Why don't you do some Internet research on Pelosi's entire comment before you mindlessly repeat a favorite conservative smear against Pelosi?
She was giving a speech to an association of county government elected officials. She was talking about the conservative attacks on the bill. She then said the US Senate was making changes to the bill, but once the bill was passed, people outside Congress would be able to see it.
So, "We (Congress) have to pass the bill (in its final form) so that you (the public) can see what's in it."

The ACA took 14 months to pass. Numerous committee hearings in public were held. There was extensive floor debate.
Contrast that with the Republican Senate where McConnell tried to pass a bill in weeks, with the details secret, no public hearings, and no senator knowing what was in the bill until hours before the vote.
