Earlier on May 9, Trump had fired James Comey from his post following which former FBI director Robert Muller was appointed by Deputy Attorney General Rod Rosenstein as special prosecutor to take over investigation into Russia's interference in U.S. presidential elections.

"In all of this, Donald John Trump has acted in a manner contrary to his trust as President and subversive of constitutional government, to the great prejudice of the cause of law and justice and to the manifest injury of the people of the United States", the article reads.

Eyewitness News asked Sherman about the fear that some Democrats have that a Pence presidency could be worse than a Trump presidency.

"The congressman is circulating the article and asking for feedback from his colleagues whose opinions he has tremendous respect for", a Sherman spokesman told Morning Consult on Monday.

House Democrats have used such "privileged" motions nearly every week since Trump's election to for votes on resolutions which would force the president to release his tax returns.

"As tempting as it is for the Democrats to push the idea that Trump could be guilty of obstruction of justice and push for impeachment, that could ultimately backfire on them-it raises public expectations, but if it doesn't happen, it looks like you tried to do something and failed", Brown wrote in his San Francisco Chronicle column over the weekend. "And the national interest requires that we do so".

The spokesperson was not able to confirm where the ad was running or how long the campaign would run. Pictured next to the bottle of Smirnoff is a Moscow Mule, a cocktail made with vodka.

"I have no illusions", he said.

The lawmaker believes there is now evidence enough to bring an obstruction charge against the president, but says he may file further articles as investigations continue.

Sherman isn't the first Democrat to look to impeach the current US president, Reps. Neither Sherman nor Green sit on the Judiciary Committee, which would investigate and debate any impeachment articles, and there is no sign the Republican-controlled House is poised to launch any inquiry that could ultimately force Trump from office.

"At that point, I expect there will be a Motion to Table, thus triggering our first impeachment-related vote", he said.

Once filed, Sherman's resolution would be the first article of impeachment introduced in the 115th Congress. However, as to Obstruction of Justice and 18 USC § 1512 (b)(3), the evidence we have is sufficient to move forward now. Rep. Al Green (D-Texas) has also said he would draft an impeachment article, and Rep. Maxine Waters (D-Calif.) has publicly advocated for such a move.
