there is no way any Senate Dem would vote money for a wall unless Upchuckee made them. No mount of pressure will change that ... as far as the House goes Ryan would stop it getting to the floor and, even if he did allow it without the 10 Dems, it would be pointless like all those bills to kill Ocare the House passed.
I think that Trump is just toying with us, because he hasn’t called out Mitch McConnell. We don’t even know if Mitch supports a wall! McConnell never tweets about immigration, including after the talks Trump had with Pelosi and Schumer. Trump’s best chance for border security was with Paul Ryan’s $1.3 trillion dollar Omnibus spending bill that he signed with no funding for new parts of the wall or security. He had control of both Houses, yet he gave Paul Ryan and Schumer everything. Schumer even said that Trump gave more than Obama!
