Grassley said he didn't think the rhetorical fight is "productive" and that the two men should "cool it." 
"And I think it would help if the president would be the first to cool it," he said during a town hall in Iowa on Monday, according to The Associated Press
Grassley, who chairs the Judiciary Committee, added that "it would be better if we stuck to the issues and leave personalities out of it." 
Corker and Trump traded fire on Sunday after the president lashed out at the GOP lawmaker in a morning series of tweets. 
But Corker's staff pushed back against the tweets, saying the president asked Corker to reconsider his decision, which he announced in late September, to retire after 2018. 
Corker also fired back on Twitter, calling the White House an "adult day care center." 
He separately told The New York Times that Trump "concerns" him and that his threats to other countries put the U.S. "on the path to World War III.”
Republican senators, who are out of Washington for the week, have largely remained mum on the feud. 
But he sidestepped when asked if he agreed with Corker's criticism of Trump. 
Corker was once considered as a potential vice president or secretary of State pick, but his increasingly sharp public criticism has appeared to rankle Trump and the White House. 
Grassley, according to NBC News, added on Monday that he has "more important things to do" than get in the middle of Corker and Trump. 
"I got more important things to do, doing my job, than to go tell Corker to keep his mouth shut or to tell the President something," the GOP senator said.
