What "this" are you referring to?  I still don't know what alleged lies you're talking about.

Is it the claim that tax rate cuts increase tax revenues to the federal government?  That's an historically documented fact. We still had deficits after the Reagan tax rate cuts, despite nearly doubling tax revenues, because Tip O'Neil's Democrats controlled the House and they increased non-defense spending by even more than the revenues increased.  I have the numbers at my fingertips if you doubt that.

Or, if you're referring to Trumps claim that 3 million illegal votes were cast, a number of studies show that his estimate is likely low.
