Trump is visiting a pharmaceutical and biotech company in Ohio to tout TrumpRx.com and speak on affordability.
Less is known about his swing through the commonwealth, however, but the trip will put Trump in Kentucky's 4th Congressional District, where he and his allies are backing primary challenger Ed Gallrein against Massie.
Massie has butted heads with the president on several high-profile White House priorities, from last July's tax and spending bill to military operations in Venezuela. The Kentucky congressman also led an unsuccessful attempt to reassert congressional war-making powers last week amid the ongoing conflict in Iran.
While the congressman hadn't taken to social media with any thoughts on Trump's trip to his district Monday afternoon, he continued to question the attacks on Iran — writing Sunday that the price of gas is rising due to the war and adding that "waging war costs American taxpayers about $1 billion a day. He ended the post by writing, "This isn't America First."
Massie appeared last month on CNN, arguing the political pressure on him is about keeping GOP House members 100% on board with the administration.
"It's really about keeping my colleagues in line," he said. "They're under no illusion that I will snap back into line because they're spending millions of dollars against me. It's going to be tough, but I'm going to win."
Trump has repeatedly resorted to name-calling against Massie and stated that the representative "must be thrown out of Congress ASAP."
The president will visit Hebron on Wednesday.
