Sunday on CBS’s “Face the Nation,” Sen. Ron Johnson (R-WI) said President Donald Trump’s  tweet today threatening a government shutdown if a wall on the U.S.-Mexico border was not funded is not “helpful.”

Partial transcript as follows:

BRENNAN: Wisconsin Republican Senator Ron Johnson joins us this morning from Green Bay. Welcome to the show. Senator, the president-

JOHNSON: Morning Margaret.

BRENNAN: – tweeted this morning that he may shut down the government if he doesn’t get border wall funding. You’re the chair of the Homeland Security Committee. Should we expect a September shutdown?

JOHNSON: Let’s hope not. I think hopefully most of the appropriation bills will actually be passed a little more-a little better prioritization of spending. So I certainly don’t like playing shut down politics.

BRENNAN: And how damaging would that be for Republicans ahead of the November race?

JOHNSON: I don’t think it’d be helpful, so let’s try and avoid it.
