U.S. President Donald Trump meets with Polish President Andrzej Duda and will hold a joint press conference following meetings at the White House.
Trump is expected to confirm reports that 1,000 additional American troops and a squadron of Reaper drones will be sent to Poland to beef up the nation's ability to defend itself amid worries about Russian military activity.
Officials say the preliminary agreement calls for building a new combat training centre in Drawsko Pomorskie and additional facilities in the future. There is a rotational force of about 4,500 U.S. troops in Poland now. They aren't permanently based there.
An aide to Duda has said that negotiations to increase American troops in Poland were successful.
