WASHINGTON (AP) — After days dominated by friction with his secretary of state and a Republican senator, President Donald Trump is trying to refocus on his top legislative priority, using a Pennsylvania visit to pitch his tax overhaul as a boon for truckers.

Trump speech in Harrisburg was to be set against a backdrop of big rigs, with lots of truckers in attendance, according to the White House. The president has been traveling the country to promote a plan that would dramatically cut corporate tax rates from 35 percent to 20 percent, reduce the number of personal income tax brackets and boost the standard deduction.

At his latest stop, Trump planned to argue that his tax reform framework would benefit truckers by lowering their tax rates, boosting manufacturing, and making it easier for families to pass their trucking businesses on to their children.

"When your trucks are moving, America is growing. That is why my administration is taking historic steps to remove the barriers that slow you down," Trump said in prepared excerpts released by the White House. "America first means putting American truckers first."

Trump is diving back into the tax fight after weeks in which his attention has shifted to rapidly emerging crises — including the mas shooting in Las Vegas and the hurricane recovery effort in Puerto Rico — as well as dramas of his own making, such as his escalating feud with Sen. Bob Corker, R-Tenn., and public tension with Secretary of State Rex TIllerson.

Taxes are the chief legislative priority for Republicans hungry for a major legislative achievement. With the 2018 campaign year looming, GOP lawmakers want something to show for their time as the majority party, and tax legislation remains their best hope.

Trump has left it up to Congress to fill in many specifics of his plan, which omits details such as the income levels for his new tax brackets.

Republicans in Congress aren't solidly behind him, with some from high-tax states balking because the framework calls for eliminating the federal deduction for state and local taxes. That deduction is claimed by an estimated 44 million people and costs the government an estimated $1.3 trillion in lost revenue over 10 years.

Fractious Republican lawmakers, especially those from New York, New Jersey and California, are wary of the potential financial hit to their constituents. They contend repealing the deduction would subject people to being taxed twice.

"They need our votes" on the tax plan, said Rep. Chris Collins, R-N.Y., a member of the group.

Discussions with House leaders on a possible compromise took place last week but are on hold, Collins and other lawmakers in the group said Wednesday. They said they were confident of a compromise.

Trump planned to highlight the tax plan's provisions aimed at encouraging international companies to bring back, or repatriate, cash that they've kept overseas. All told, there's more than $1 trillion in cash held abroad by S&P 500 companies, according to Deutsche Bank.

"We will eliminate the penalty on returning future earnings back to the United States and we will impose a one-time low tax on money currently parked overseas so it can be brought back home to America, where it belongs," Trump said in the prepared excerpts. He added that his Council of Economic Advisers estimates that the change "would likely give the typical American household a $4,000 pay raise."

The $4,000 in additional income estimate comes from a back of the envelope calculation by White House economics adviser Kevin Hassett based on companies returning 71 percent of their foreign profits over the course of eight years.

This estimate appears to assume that the returned profits would flow to workers in the form of higher wages. But many economists say much of it would likely be returned to investors in the form of stock dividends and buybacks.
