WASHINGTON — Vice President Joe Biden will travel to Latvia over the summer in what is likely one of his last foreign trips as vice president.

Biden spoke on Wednesday to Latvian President Raimonds Vejonis. The White House says Biden accepted an invitation from Vejonis to visit the country during the conversation.

Biden has traveled frequently to the Baltic states to reassure them of U.S. support in light of Russia's aggressive actions in Ukraine, another country on Russia's border. The White House says Biden told Vejonis that the U.S. has an "unshakeable" commitment to the Baltic nations' security.
