Saturday marks President Trump's first 100 days as president, but it also marks Barack Obama's first 100 days as a former president.

So how has Obama done? He's chalked up his own share of wins and losses:

Syria uses chemical weapons after Obama said they were gone

An attack by the Syrian government on the people of the Idlib Provence on April 4 killed 89 people. Early videos of the victims indicated that the weapon was a chemical or nerve agent, and those fears were confirmed by the Organization for the Prohibition of Chemical Weapons just weeks later.

In 2013, the Obama administration and Russia jointly brokered a deal with Syria that called for the destruction of all of the country's chemical weapons. In 2014, then-Secretary of State John Kerry said in a television interview that, "We got 100 percent of the chemical weapons out."

The chemical weapons attack seemed to indicate that wasn't true, although some still hold out as a possibility that Syria did in fact clear out all its chemical weapons only to rebuild their stockpiles at a later date.

Still, no other event in the last 100 days has discredited the Obama legacy as Syria's chemical attack.

"Unmasking" of Trump transition officials

The Russian investigations that have been ongoing since the late fall of 2016 veered into surveillance issues early in 2017, after President Trump tweeted that his campaign had been "wiretapped" by Obama.

While there is still no evidence Obama administration officials were spying on Trump's team for political reasons, reports later said Obama's national security adviser, Susan Rice, played a role in identifying some of the Trump officials who were caught up in surveillance of foreign officials.

And while Rice said she never unmasked anyone for political reasons, that leaves open the question of who might have leaked the identities of those who were unmasked. Rice said it was not her.

News on Iranian prisoners released by Obama

President Obama released several prisoners as part of an exchange with Iran, as part of the Iran nuclear agreement. The prisoners being released "were not charged with terrorism or any violent offenses," according to the administration.

But a recent report by Politico shows that the release of some Iranian-born prisoners as part of the deal was broadly misrepresented by the Obama administration.

The new report says, "In reality, some of them were accused by Obama's own Justice Department of posing threats to national security. Three allegedly were part of an illegal procurement network supplying Iran with U.S.-made microelectronics with applications in surface-to-air and cruise missiles like the kind Tehran test-fired recently, prompting a still-escalating exchange of threats with the Trump administration."

Obama's questionable $400,000 speech

Obama once said that at some point, rich people have "made enough money." But that didn't stop him from charging $400,000 for a speech on Wall Street that riled up some Democrats, who said it looked bad at a time the party is trying to rebuild from the disastrous 2016 election.

Sen. Bernie Sanders, I-Vt., admitted that Obama's speech "just does not look good."

Obamacare survives ... for now

One of the few bright spots for Obama is that his signature law, the Affordable Care Act, has not been repealed by Republicans.

Obama sacrificed the re-election chances of numerous representatives and senators when the legislation passed in 2009. But as tough as it was to pass the law, Republicans are showing it may be even harder to get rid of it.

While the law survives, the vital signs for Obamacare are still mixed. The law is still insuring millions of people, but there are fewer and fewer choices for people in many states, as insurers have pulled out due to lost profits.

The Trump administration has threatened to make it even harder on insurers by not providing cost-sharing subsidies, and Republicans are still angling to repeal the law.
