President-elect Trump on Sunday made public his support for Republican lawmakers to pass key components of his agenda into law with a single reconciliation bill, previewing what is expected to be a lengthy and complicated legislative task in the first few months of his second term.

“Members of Congress are getting to work on one powerful Bill that will bring our Country back, and make it greater than ever before,” Trump posted on Truth Social.

“We must Secure our Border, Unleash American Energy, and Renew the Trump Tax Cuts, which were the largest in History, but we will make it even better – NO TAX ON TIPS,” he added, making the dubious claim that tariffs on foreign imports would offset for the cost of new spending and tax cuts.

“Republicans must unite, and quickly deliver these Historic Victories for the American People,” Trump posted. “Get smart, tough, and send the Bill to my desk to sign as soon as possible.”

Trump’s post on social media came one day after Speaker Mike Johnson (R-La.) told fellow House Republicans that the president-elect preferred that lawmakers pass his agenda in one large reconciliation bill, rather than dividing it into two pieces of legislation.

Some Republicans had suggested the new Congress could quickly pass a reconciliation bill with added border security and pass a second bill focused on tax policy later in the year.

Passing legislation via the reconciliation process would require a simple majority in both chambers of Congress, meaning Republicans would not require any Democratic support.

Johnson told Fox News on Sunday that he was aiming for the House to vote on the reconciliation package in the first week of April.
