Gee there are so many to choose from. How about when he said he knew nothing about the stormy Daniels payoffs and then a recording came out of him discussing it with his lawyer! That’s a pretty good one.
So the worst “lie” you can come up with is one about a dumb tart his lawyer paid off in a perfectly legal NDA? And the only “proof” you have is a violation of attorney-client privilege?
That was just the first one that popped in my head... you want a political one??
How about “we will build a Great Wall and Mexico will pay for it” easy! Or repeal and replace Obamacare so quickly and so easily. Wouldn’t those be on par with Obama’s “keep your plan keep your doctor” lie
He is trying to build a Great Wall, but can not control Dems court challenges to block it, or unwillingness to pay for it. Mexico is paying for it through tariffs and losing jobs. He actually promised that Mexico would help pay for it, or else they would be punished through punitive measures like tariffs, something you idiots always leave out.
He also isn’t responsible for Congress unwilling to repeal Obamacare. He would had signed it if it passed.
So the biggest “lies” you have are Congress being unwilling to act.
