Applause.
President Trump waves to the crowd during the applause and then signs the repeal.
"I just kept my promise to repeal Obamacare. Over the next few months, the Executive Branch will follow existing legislation to build the wall and enforce immigration law, and we will negotiate with the democrats on any potential replacement for Obamacare.
That would be glorious!
If he followed it up with...
“US Marshals, arrest all these people (indicating the Obams, Clintons, and any Obama and Clinton associates present) on charges of corruption and treason. Take them to Florence Supermax to await charges and trial.”
It would be even better. LOL
