What were the four biggest "scandals" that Republicans complained about during the 8 years of President Obama's presidency?
1. Fast and Furious - A Justice Department sting operation that allowed illegal gun sales in order to track the sellers and purchasers, who were believed to be connected to Mexican drug cartels. Some guns were subsequently used in crimes.
2. Bengazi - Following protests due to an anti-Muslim video, an attack on a US diplomatic compound in Bengazi Libya lead to the death of U.S. personnel.
3. Clinton's E-mail Server - Hillary Clinton was discovered to have conducted official State Department business on a private e-mail server.
4. Clinton Foundation - Hillary Clinton's charitable foundation received donations from foreign donors, which Republicans alleged was tied to diplomatic favors.
Now, each week, the Trump administration officials engage in public business using private Trump assets and e-mail accounts. Trump's twitter account is treated as both an expression of federal policy, yet Trump frequently blocks critical comments. Members of the Trump family such as Kushner still use private e-mails accounts when conducting diplomatic business with impunity.

The Trump foundation has been used to launder political donations and bribes to Republican candidates. Likewise, Trump campaign contributions are often paid toward private Trump businesses.

As to Fast and Furious and Bengazi, Trump has already repeatedly thrown his military under the bus for botched operations. Likewise, Syria is an ongoing fiasco.

Finally, the above ignores the daily efforts to obstruct justice and subvert the DOJ and ICE into Trump's personal security force to pursue political vendettas, as well as the rampant use of taxpayer dollars for private and personal luxuries by his cabinet secretaries.
In short, in almost every week during the Trump presidency, he manages to exceed 8 years of so-called "scandals" under the Obama administration with Hillary Clinton as Secretary of State.
