President Trump doesn’t need any more problems with Congress at the moment. His repeal and replace health care bill will likely not pass either house in its current form.
But now the appropriation bill necessary for the operation of the Federal government until the fall is in trouble because Democrats are objecting to money in the bill for the President’s wall along with the U.S.-Mexican border.
There may be a legislative compromise available, but for now, Democrats are claiming they would stop the “keep the government open” appropriation bill if it includes money for the wall. That may be overkill and Democrats could look “Ted Cruz” extreme, but they have picked an issue that has little public or Republican establishment support, although rank and file Republicans like it.
Unfortunately, Trump not only promised a wall, but also that Mexico would pay for it, and almost no one believes that. Hence, another promise is in some trouble.
