This morning marks the biggest domestic challenge of President Donald Trump's second term in office.The question is whether he can close the deal with skeptical House Republicans and convince them to support the so-called "big, beautiful bill." Its doubtful the bill has the votes to pass right now. House Speaker Mike Johnson, R-La., intends to pass the bill before releasing members for the Memorial Day recess.HOUSE GOP CHANNELS NIGHTHAWKS AS THEY TRY TO PASS TRUMP'S BIG, BEAUTIFUL BILLOutstanding issues remain on state and local tax deductions (SALT), Medicaid work requirements, asking states to pick up additional health care costs and overall spending.Its about the math. House Republicans can only lose three members and still approve the bill.Johnson wants to vote as early as Thursday and maybe even tomorrow.TRUMP HEADS TO CAPITOL HILL TO PUSH BIG, BEAUTIFUL BILLThe House Rules Committee will convene at 1 a.m. ET on Wednesday to begin prepping the package for the floor. There are several reasons for this, but lets begin with the parliamentary one.The Budget Committee wrapped up justbefore midnight Sunday. The rules allow Democrats two full days to file their paperwork and viewpoints after that meeting. So, they had all day Monday and all day Tuesday. The Rules Committee needs an "hour" to announce its formal meeting. So, the "official" announcement of the Rules Committee meeting on Wednesday will go out just after 12:01:01 a.m. ET Wednesday. That triggersat 1 a.m.ET meeting Wednesday.Here are the other, more practical reasons.Republicans need all the time they can get. There is talk of trying to vote on the floor late in the day on Wednesday. Well see about that. But the early Rules Committee meeting time makes that a possibility.Second of all, its possible the Rules Committee meeting could consume the entire calendar day of Wednesday. Streams of lawmakers from both sides will file into the Rules Committee to propose various amendments. This is a protracted process.But by the same token, the meetingat 1 a.m.ET could diminish attendance. After all, who wants to show upat 1 a.m.ET for a meeting and maybe discuss your amendmentat 6:30 a.m. ET? You get the idea.We expect Trump to meet with Republicans for about an hour and a half this morning. Well see if that moves the meter.
