At the White House on Monday morning, President Trump did not respond to questions from reporters about his tweets against Cummings and the city of Baltimore.
But earlier in the day, the President again went on Twitter and teed off against the Charm City and Rep. Elijah Cummings (D-MD).
On Sunday, Mr. Trump called Cummings 'racist.'
"If racist Elijah Cummings would focus more of his energy on helping the good people of his district, and Baltimore itself, perhaps progress could be made in fixing the mess that he has helped to create over many years of incompetent leadership," the President tweeted.
With Baltimore on pace to set a new record for the number of homicides in a year, Gov. Hogan said the political rhetoric on Twitter was not helpful.
"I mean quite frankly, what is the President doing and what is the Congress doing?" Hogan said on WBAL Radio.
With the U.S. House on recess, nothing will get done anytime soon - as Democrats stood up for Cummings from back in their districts.
"The President is having a public temper tantrum because Rep. Cummings is holding him accountable," said Rep. Terri Sewell (D-AL).
