Sen. Chuck Grassley, R-Iowa, offered a welcome to President Donald Trump before his visit to Iowa next week, but said he wouldn't be able to attend a planned rally, The Hill reported Saturday.
Grassley gave the president the message in a tweet Saturday, explaining he had recorded phone calls encouraging constituents to attend.
The rally, set to take place in Cedar Rapids, will be Trump's fifth since taking office in January. Grassley made headlines this week when he announced Wednesday he was calling for the Senate Judiciary Committee, which he chairs, to launch an investigation into the president's firing of former FBI Director James Comey.
Several Republicans were surprised at Grassley's move to begin another investigation into a subject that already had multiple investigations looking into the matter.
"I'm sure it's being pushed rather hard by Democrats because I don't know one Republican pushing that," Sen. Orrin Hatch, R-Utah, said Wednesday. "It's not that they don't want to have an investigation, they don't see a need for it."
