Before-and-after photos show dramatic differences in presidents and first families after time spent in White House

Reagan left a legacy as a wildly popular president that was built on victories such as surviving an assassination attempt, cutting taxes and federal spending, and successfully negotiating peace deals including a treaty with Soviet leader Mikhail Gorbachev to eliminate intermediate-range nuclear missiles.

Though Reagan is still lauded by conservative politicians, the administration's legacy is still marred by several policy failures decades after Reagan left office, including the administration's dismissal of the HIV/AIDS crisis, which Reagan only mentioned in public in 1985, years after the beginning of the epidemic, before adding to his agenda in 1986, when more than 400,000 Americans were already living with HIV.

Another point of contention includes the November 1986 Iran Contra Affair, in which Reagan admitted that the US had sold weapons to Iran in hopes to secure the release of six US hostages and some of the money was secretly funneled to the right-wing Contras, who were seeking to overthrow Nicaragua's socialist Sandinista government.

Bush was the first incumbent vice president to be elected president in more than 150 years, when Martin Van Buren replaced Andrew Jackson.

His term in office included the military and diplomatic victory of Desert Storm, which defeated the Iraqi Army after President Saddam Hussein invaded Kuwait, but voters were still discouraged by the weak economy, rising violence in inner cities, and ongoing national debt.

Clinton, a former Arkansas politician, handily defeated Bush despite accusations he dodged the Vietnam War draft and rumors of infidelity that plagued his campaign.

Clinton was not only the first baby boomer president but also the first Democratic president since Franklin D. Roosevelt to win a second term.

His two terms in office began amid several positive rates in American life, including the "lowest unemployment rate in modern times, the lowest inflation in 30 years, the highest home ownership in the country's history," and falling crime rates. Clinton also achieved a budget surplus.

In 1998, Clinton's sexual relationship with Monica Lewinsky, a White House intern, caused him to become the second US president to be impeached by the House of Representatives.

He was tried in the Senate and found not guilty of the charges.

The Clintons remained in the public eye for years after the presidency, as Hillary would later serve as a senator, Secretary of State, and the 2016 Democratic presidential candidate.

Months after his inauguration, fallout from the September 11, 2001 terrorist attacks on the World Trade Center and the Pentagon dominated Bush's presidency.

Bush promised a massive US response to quash organized terror, and formed the Department of Homeland Security before sending American forces into Afghanistan, where they successfully broke up the Taliban.

Another counterterrorism effort saw American forces invade Iraq, where they captured Iraqi President Saddam Hussein. The conflict caused great disruption in the region, which Bush promised his second term would focus on solving.

However, by 2004 the Senate Intelligence Committee had concluded that the US invasion and Iraq War were founded on false and exaggerated intelligence.

Though much of the blame for the Iraq War was initially pointed at the CIA, Bush's popularity and public image nosedived in the final years of his presidency.

At the start of the war, 23% of Americans said sending troops to Iraq was a mistake, a rate that rocketed to 40% after six months in the war. As of June 2015, 51% of Americans said the mission was a mistake.

In his first term, Bush's approval ratings spiked to around 90% after the 9/11 attacks and fell to around 30% amid the fallout for the causes in Iraq he championed.

Bush's controversial reputation has since softened as the former president and first lady made appearances at large Washington events. Jenna Bush Hager has since become a prominent television personality in her role as a host on NBC's "Today."

Obama moved into the White House with his young family, which included 9-year-old Malia and 6-year-old Sasha.

Aside from achieving the title of the first African-American president in US history, Obama's legacy is largely outlined by policy victories including the Paris climate change agreement, the Affordable Care Act or 'Obamacare,' and immigration's Deferred Action on Childhood Arrivals policy.

After two terms that included consistent popularity and various domestic and international victories, President Donald Trump targeted his predecessor's legacy, unwinding his signature policies in climate change, healthcare, and immigration.
