Secretary of State Tom Schedler is asking President Donald Trump to reverse a last-minute decision by the Obama administration to designate election systems as critical infrastructure.
Pres. Obama imposed sanctions on Russian officials and intelligence services in retaliation for Russia's interference in the U.S. presidential election.
The White House says that during the 8 p.m. address Obama will provide an update on the attack that killed 14 and wounded 21, and will also discuss the broader threat of terrorism.
The agreement — signed by Iran, the U.S. and five other world powers — seeks to dismantle Iran's nuclear program in exchange for billions of dollars in relief from sanctions.
The Obama-Clinton get-together comes after the former secretary of state gave an interview presenting a contrasting vision for America's role in the world ahead of a possible 2016 White House bid.
Obama says he won't allow the U.S. to be dragged into another war in Iraq. But he says the U.S. will protect Americans and prevent terrorists from having a safe haven.
The trip comes as Obama is dealing with a series of high-profile tests of his presidency, from Eastern Europe to the Middle East to the Southern border.
