The IRS scandal is only growing, which means members of Congress are calling for all kinds of investigations and the firings of those involved.

Below is a recap of who is proposing what in terms of an investigation:

* House Ways and Means Committee leaders Reps. Dave Camp (R-Mich.) and Sandy Levin (D-Mich.) say their committee will spearhead the House investigation.

* Senate Finance Committee Chairman Max Baucus (D-Mont.) says his committee will investigate, as well.

* Senate Minority Leader Mitch McConnell (R-Ky.) says the investigation of the IRS’s wrongdoing should focus on the White House and that the Obama Administration should cooperate fully and make its officials available.

* Louisiana Gov. Bobby Jindal (R) and Wisconsin Gov. Scott Walker (R), leaders of the Republican Governors Association, have called for a special prosecutor to determine what laws might have been broken, along with the firing of anyone responsible.

* House Oversight Committee Chairman Darrell Issa (R-Calif.) has said the White House shouldn't lead the investigation.

* Sen. Rand Paul (R-Ky.) has proposed a resolution condemning the IRS and calling for an investigation.

* Sen. Marco Rubio (R-Fla.) and Rep. Mike Turner (R-Ohio) have filed matching bills calling for the firing of any IRS employee who “willfully” violates the constitutional rights of Americans.

* Rep. Bruce Braley (D-Iowa), who is running for Senate, has called for the resignation of Lois Lerner, the director of the IRS's tax-exempt division. “'Sorry' just doesn’t cut it,” Braley said. “There need to be consequences for this violation of the public trust, starting with the resignation of Lois Lerner.”

* McConnell and Sen. Roy Blunt (R-Mo.) have called for the removal of acting IRS commissioner Steven Miller, who reportedly learned about the targeting in 2012. “If the reports are accurate that Steven Miller knew about the IRS’s egregious targeting of conservative groups last year and misled members of Congress about those actions, he should step down or be removed immediately,” Blunt said.

* Sen. Dean Heller (R-Nev.) wrote a letter to Health and Human Services Secretary Kathleen Sebelius requesting that no more funds be used for the hiring of IRS agents to help implement Obamacare until the scandal is investigated.
