Marc T. Short (born March 3, 1970) is an American political advisor who was chief of staff to Vice President Mike Pence.

He was a senior fellow at the Miller Center of Public Affairs, a CNN contributor, chief of staff to Senator Kay Bailey Hutchison, and the House Republican Conference.

[6] In a column for the paper, Short "disparaged people living with HIV and AIDS," stating "the propaganda campaign ignited by gay activists and carelessly perpetuated by journalists whose intent is to scare all heterosexuals into believing they are prime targets for contraction of the disease.

When Hutchison ran for Governor of Texas, Short started working for then-Congressman Mike Pence, who named him chief of staff for the House Republican Conference in 2009.

[14] Short announced he would leave the White House post in the summer of 2018, citing "diminishing returns" of pushing President Donald Trump's agenda.

[1] On November 20, 2019, Short issued a statement rebutting the sworn testimony given that same day before Congress by US Ambassador to the European Union Gordon Sondland.

Sondland claimed while meeting with Pence that the two discussed the alleged "quid pro quo" that was at the heart of the impeachment inquiry before the House.

"[17] Later that evening during Cuomo Prime Time, the statement was described as being well crafted and that it didn't deny that Pence already knew about Trump's requests.

In internal discussions, Short also criticized the administration's public health response in a broader policy level, arguing that it damaged the economy and harmed Trump's re-election chances.

[19] As Short and his wife hold stock in various pharmaceutical and medical companies connected with the Pence task force's work, this raised concerns of potential conflicts of interest.
