discussed this. george w. bush. and former president barack obama reportedly hasn't even talked to president trump since he left the white house on inauguration day. but listen to what he told the u.n. in 2016. >> a nation ringed by walls would only imprison itself. >> and there's more. president trump has even claimed falsely that ronald reagan tried for eight years to build a wall or a fence. oh, yeah? okay. i want you to listen to what reagan actually said. this is from a 1980 presidential debate. >> rather than making them or talking about putting up a fence, why don't we work out some recognition of our mutual problems and make it possible for them to come here legally with a work permit and then while they're working and earning here, they pay taxes here. >> that was president reagan. can we please play that again.
