But while the nature of the controversies were different, we found at least five examples of congressional investigations in which congressional Republicans used the investigation process to put Obama on the political hot seat:
• Loans to the solar company Solyndra. The company collapsed after taking a $535 million federal loan guarantee, and Republicans noted that a campaign bundler for Obama was a key investor.
The loan default prompted an investigation by the House Energy and Commerce Committee.
• Alleged political bias at the Internal Revenue Service. This controversy involved charges that IRS officials were unfairly targeting conservative groups for unusual scrutiny in applications to become a tax-exempt organization.
This attracted an investigation by the House Oversight and Government Reform Committee, the Senate Finance Committee, and a Senate Homeland Security and Governmental Affairs subcommittee.
• The Benghazi consulate terrorist attack in 2012, in which four Americans died, including the U.S. ambassador.
The circumstances surrounding the attack were investigated by the Senate Intelligence Committee, the Senate Homeland Security and Governmental Affairs Committee, several House panels led by the House Intelligence Committee, and a specially created House Benghazi committee. In 2015, the specially created committee called Hillary Clinton -- who had been secretary of state during the attack and who was widely expected to run for president -- for a full day of televised testimony. (The two Senate investigations were actually conducted by a Democratic majority of a Democratic president.)
• The "gun-walking" program known as Fast & Furious, in which the Bureau of Alcohol, Tobacco, Firearms and Explosives, partly during Obama’s presidency, allowed guns to be sold to Mexican nationals in the hopes of tracking down drug cartel leaders.
The program was investigated jointly by the House Oversight and Government Reform Committee and the Senate Judiciary Committee.
• The botched 2014 launch of the Affordable Care Act website, healthcare.gov. At first, the website was largely inoperable, though the government was eventually able to fix it.
The rollout was the subject of hearings by the Energy and Commerce Oversight and Investigations Subcommittee, the Senate Finance Committee, the House Ways and Means Committee, and the House Oversight and Government Reform Committee.
It’s worth noting that prior to becoming president, Trump himself tweeted actively about these five controversies, mostly to cheer on the probes or to criticize the Obama administration.
