No serious person has ever taken the wall seriously (can anyone even define what "the wall" entails), it was always bullshit, which is why it took General Kelly about 2 seconds to cast the idea aside when he took over homeland security, and why almost nobody in the GOP house or GOP senate took it seriously, let alone advocated for it in the two years that they controlled the entire federal government.
LOL at people who thought Mexico would pay for it....now Trump is dropping the price he wants from Dems from 5 billion to 2 billion, like it's one of his condos where someone was murdered. Sam Nunberg explained where the idea of "building the wall" came from (spoiler alert, it didn't come from national security experts):
"Sam Nunberg told the
New York Times getting Trump to talk about building a wall was the easiest way to get him to discuss immigration on the campaign trail.
Nunberg who advised Trump during his 2016 presidential campaign and was later
subpoenaed by special counsel Robert Mueller as part of his investigation of the Russia probe, cited a conversation with fellow advisor Roger J. Stone Jr.
"How do we get him to continue to talk about immigration?" Nunberg said. "We're going to get him to talk about [sic] he's going to build a wall."
What was meant to serve initially as a way to encourage Trump to talk about immigration now sits at the center of the current
partial government shutdown. All the while, the rhetoric around how or what exactly will be built has continued to change.
Outgoing White House chief of staff
John Kelly said the addition to the southern US border wouldn't even actually be a wall.
