"There would not be an investigation into Benghazi, there would not be an investigation into the IRS were there not a Republican House," said Romney on MSNBC’s “Morning Joe” when asked if it was appropriate to fundraise off the probe.

“So to say, look, elect Republicans, so that we have these kinds of investigations is appropriate," he added.

Democrats have slammed Republicans for sending out a fundraising pitch off the new House select committee investigating the attack. The National Republican Campaign Committee has posted a number of blogs about the investigation with links to fundraising pages on the website

The chairman of the committee, Rep. Trey Gowdy (R-S.C.), has called on his Republican colleagues to refrain from fundraising off the investigation. But Speaker John Boehner (R-Ohio) sidestepped questions about the money pitch, saying that his focus was on “getting the answers” to what happened during the deadly attack that killed four Americans.

The House voted Thursday to impanel a select committee to investigate the events surrounding the attack after previously undisclosed White House emails came to light last week. 

An email from Deputy National Security Adviser Ben Rhodes to then-U.N. Ambassador Susan Rice telling her to highlight the role of an anti-Islam YouTube video in sparking protests had not been given to Congress despite an earlier subpoena. Republicans say the emails show the White House was attempting to downplay the terrorist nature of the attacks ahead of the presidential election.

Democrats have criticized the select panel saying it is unnecessary and a waste of taxpayer dollars.

Romney, though, said the investigation was appropriate.

"I think what the Republicans have every right to say, and is appropriate to say, is that if Republicans were not in the Congress, if Republicans did not have a majority in the Congress, there would not be an investigation in to Benghazi," he said.

"I think there are questions that have to be answered, that have not yet been answered, that the White House has apparently withheld certain information," Romney added.
