Washington (CNN) President Donald Trump's tweet blaming Attorney General Jeff Sessions for bringing indictments against two Republican lawmakers could be grounds for removing him from office, CNN senior legal analyst Jeffrey Toobin said Tuesday.

"This tweet alone may be an impeachable offense. This is such a disgrace," Toobin said on CNN's "New Day."

The President tweeted Monday , "Two long running, Obama era, investigations of two very popular Republican Congressmen were brought to a well publicized charge, just ahead of the Mid-Terms, by the Jeff Sessions Justice Department. Two easy wins now in doubt because there is not enough time. Good job Jeff."

In his tweet, Trump was referring to Republican Reps. Duncan Hunter of California and Chris Collins of New York, his earliest supporters in Congress, who were indicted last month within two weeks of each other on unrelated charges. Both have pleaded not guilty.

The President's tweet is "so contrary to the traditions of the Department of Justice," Toobin said Tuesday.
