The rare but not unprecedented US move to impose sanctions on a head of state would come just a day after Russian forces invaded Ukraine, assaulting by land, sea and air in the biggest attack by one state against another in Europe since World War II.
White House spokeswoman Jen Psaki on Friday said the decision to target Putin, Lavrov and other officials was made after President Joe Biden had a phone call with European Commission President Ursula von der Leyen.
Earlier on Friday, European Union states and Britain agreed to freeze any European assets of Putin and Lavrov, as Ukraine's leader pleaded for faster and more forceful sanctions to punish Russia's invasion of his country.
The US has in the past imposed sanctions on heads of state, including on Venezuela's Nicolas Maduro and Syria's Bashar al-Assad.
Putin urged Ukraine's military to overthrow its political leaders and negotiate peace on Friday, as authorities in Kyiv called on citizens to help defend the capital from a Russian assault its mayor said had already begun.
The sanctions targeting Putin would be the latest punitive action from Washington over Russia's aggression against Ukraine.
The US on Thursday imposed sanctions on Russia's two biggest banks, among others, and members of the elite.
It followed action on Wednesday that designated the company in charge of building Russia's Nord Stream 2 gas pipeline, and Tuesday's move, which also targeted Russian banks and elites.
