NBC's host Chuck Todd criticized on Sunday what he called a "cynical tweet" from former House Speaker Newt Gingrich, which questioned where special counsel Robert Mueller's reported grand jury in Washington, D.C., might be subject to bias.

Gingrich, an avid supporter of President Trump, seemed to take issue with the location of the grand jury because the population of Washington, D.C., overwhelmingly voted against Trump in the 2016 election, versus nearby West Virginia.

"President Trump got 68.63% in West Virginia, 4.8% in Washingtoin DC. Guess where Mueller has a grand jury? Guess how biased it will be?", Gingrich tweeted.

In response, Todd, host of "Meet the Press," tweeted, "Such a cynical tweet on so many levels."

"Apparently all justice is partisan? If that's what you believe, the Republic is already doomed," he added.

Last week it was reported that Mueller, whose federal probe is investigating Russian interference in the 2016 election and possible collusion with the Trump campaign, had tapped at least two grand juries, which can issue subpoenas. They are reportedly located in D.C., as well as Virginia. Trump also lost Virginia to Hillary Clinton in the presidential election, but by a smaller margin.

Gingrich's concern with the D.C. grand jury is shared by others, including famed lawyer Alan Dershowitz, who said it could give Mueller a "tactical" advantage over Trump.

Meanwhile Preet Bharara, a former U.S. attorney fired by Trump, mocked Gingrich over his "sparkling legal analysis."
