President Trump this morning tweeted about his trip to Cincinnati today, saying he plans to meet with "ObamaCare victims" and talk about health care, as well as infrastructure.

That's a shift from how the White House had pitched the trip earlier this week, saying he would be talking about "inland waterways" at Cincinnati's Rivertowne Marina in the city's East End.

“We have 12,000 miles of inland waterways in the United States,” Gary Cohn, director of Trump’s National Economic Council, told a group of infrastructure reporters on Sunday. “It's a critical component of our nation's transportation infrastructure. It relies primarily on federal funding and includes levees, dams, locks, and ports. They're all getting old right now and they're not as efficient as they could be."

At a White House briefing on Monday, spokeswoman Sarah Sanders did not offer any specifics on Trump's waterways plan, but said the president will "speak about his wide-ranging vision for rebuilding our country, with a special focus on repairing our 12,000-mile inland waterway system."

Trump's visit comes amid the firestorm centering on former FBI Director James Comey, who testifies to Congress Thursday.

It will be Trump's first visit to Cincinnati as president, and his first stop in the Queen City since he kicked off his nationwide victory tour at U.S. Bank Arena on Dec. 1.

Wednesday's event is not open to the public, nor is it located anywhere near a locks and dam – the closest one of those being 30 miles up river in Clermont County.

Trump's visit comes as Comey prepares to testify before the Senate Intelligence Committee on Thursday about his conversations with the president before the Republican fired the top law enforcement administrator last month.

Trump lost Hamilton County in the November election, but the Republican dominated in every bordering county in Ohio, Kentucky and Indiana. His victory in Ohio played a key part in propelling Trump to the White House.

The president then wrested control of the state party from Gov. John Kasich in January, when Trump-backed Cincinnati native Jane Timken was voted Ohio Republican Party chair.

Trump repeatedly talked glowingly about Cincinnati during his campaign, recalling that one of his first real estate ventures was in Bond Hill in the early 1960s.
