“The president is his own worst enemy,” he said in an interview on MSNBC. “He is going to basically hang himself 140 characters at a time on a tweet."

"That has to come to an end,” the No. 2 Senate Democrat continued. “I hope it comes to an end. But until then, this is what we have to put up with.”

Durbin hit Trump for his tweet earlier Thursday decrying the appointment of a special counsel as a "witch hunt", calling the tweet "standard operating procedure in the Trump White House.”

“The night before they say something responsible and thoughtful. And then sometime in the middle of the night or the early-morning hours, the president tweets the exact opposite," Durbin added.

Durbin's comments on Trump's use of Twitter were largely in response to the president's tweets earlier in the day, saying that no similar investigation for "illegal acts" existed for both former Democratic presidential nominee Hillary Clinton Hillary Diane Rodham ClintonHillicon Valley: FBI chief says Russia is trying to interfere in election to undermine Biden | Treasury Dept. sanctions Iranian government-backed hackers The Hill's Campaign Report: Arizona shifts towards Biden | Biden prepares for drive-in town hall | New Biden ad targets Latino voters FBI chief says Russia is trying to interfere in election to undermine Biden MORE or former President Barack Obama Barack Hussein ObamaThe Hill's 12:30 Report - Presented by Facebook - Don't expect a government check anytime soon Trump appointees stymie recommendations to boost minority voting: report Obama's first presidential memoir, 'A Promised Land,' set for November release MORE.

“With all of the illegal acts that took place in the Clinton campaign & Obama administration, there was never a special councel [sic] appointed!" Trump tweeted.

The Justice Department on Wednesday appointed former FBI Director Robert Mueller as a special counsel to probe Russian meddling in the 2016 presidential race.

Trump’s tweets were in stark contrast to the response the White House press office issued on his behalf Wednesday, in which Trump said: “A thorough investigation will confirm what we already know – there was no collusion between my campaign and any foreign entity."
