But a Democrat majority House is not a lever of government for a conservative Republican President, and the House has most of the control over funding and appropriations of funding.
Which is the crux of Carlson's lament...that Pres. Trump has squandered the best opportunity to get the border wall funding via a GOP majority, and that his inability to master the inner workings of government is the reason.
Now the border wall funding faces a much more difficult path with even less chance of success, despite it being a core part of Trump's 2016 campaign.
Its fair criticism.
