During his trip overseas to attend the G-7 Summit in June, President Barack Obama will visit other European countries and meet with leaders to mark the anniversaries of several major events, USA TODAY reported.
In addition to the Group of Seven nations ceremony, Obama will make special stops in Poland and France.
In Warsaw, the president will celebrate the country's 25th anniversary of breaking from communism and in Normandy, he will mark the 70th anniversary of the D-Day invasion.
From June 4 to 5, Obama will be in Brussels with leaders from Great Britain, France, Italy, Canada, Japan, and Germany. The event was changed from eight nations to seven following Russia's intervention in Crimea and was originally scheduled in Sochi.
"The (G-7) leaders will discuss their broad shared economic, security and development agenda, and follow up on their March 24th discussion in The Hague on the situation in Ukraine," said White House spokesman Jay Carney.
"The President greatly appreciates the sacrifices made by our veterans and their families, and he looks forward to honoring them, along with the contributions of all the allies."
Oh Thursday, hundreds of thousands of pro-Russian supporters marched through Red Square to celebrate May Day, holding up signs that read "Let's go to Crimea for vacation" and "Putin is right," according to Salon.
In March, Vice President Joe Biden visited Poland to express his support and solidarity with the region and Russia continues to intervene with Crimea and Ukraine.
