President Donald Trump will take Air Force One to Ohio — then likely on to his South Florida resort — on Thursday to try breathing life into an infrastructure plan his senior aides now say will take multiple years to bring about.

The White House hopes to get some — but not all — of his $1.5 trillion package through Congress and signed into law this year. One senior administration official said Wednesday that White House aides expect a “strong push” to get a “big chunk” of the infrastructure plan to his desk by the end of 2018.

“We never anticipated this would be a quick or easy process,” the senior official said. “The president is in this for the long haul,” he added, saying the White House now expects parts of the package will have to wait for legislative action next year.

House Speaker Paul D. Ryan said recently he intends to move an infrastructure overhaul package in multiple bills. The senior administration official said the White House strongly supports that approach.
