Another day another lie

At his rally Pres.Trump said negotiating deals isnt easy.
Yet just in March of 2016 he said it was so easy.
Why cant he just tell the truth...and our 401k's...well I dont need him for another 4 yrs to keep mine. Recession is possibly coming. He cant take credit for good economy only..it is under his watch as Pres. so yes it would be his fault
