President Donald Trump left the G-7 summit venue in Sicily. The international meeting concluded on May 27.
The president tweeted that he would make a “final decision” on the Paris climate deal next week.
Under the 2015 Paris Agreements, countries pledge to reduce carbon emissions. The United States is still deciding if it wants to stay in the agreement.
Before making his way back home, Trump is set to visit American troops at the Naval Air Station Sigonella.
He is due to arrive in Washington later in the day after concluding a nine-day tour of the Middle East and Europe. It is his first foreign trip since taking office.
Unlike other G-7 leaders, he is not expected to hold a news conference before flying out.
