Trump to America: trust me on the border wall

President Trump tweeted this morning:

"I am reading that the great border WALL will cost more than the government originally thought, but I have not gotten involved in the........design or negotiations yet. When I do, just like with the F-35 FighterJet or the Air Force One Program, price will come WAY DOWN!"

The background: the estimated price tag of Trump's wall keeps getting higher and higher, as Axios noted last month. It's gone from $4 billion in 2015 (Trump) all the way up to Homeland Security saying nearly $22 billion in a report released by Reuters on Friday. That's not even the ceiling, as MIT estimates it will cost between $27-40 billion.

Why it matters: Trump is hoping that the public will trust him enough not to revolt against a potentially shocking price tag, enabling Congress to build the wall without a political mess. And he thinks the examples of the F-35 fighter and Air Force One will get him across that finish line.
