Special U.S. envoy Steve Witkoff said Sunday that Russian leader Vladimir Putin agreed at his summit with President Donald Trump to allow the U.S. and European allies to offer Ukraine a security guarantee resembling NATO's collective defense mandate as part of an eventual deal to end the 3 1/2-year war.

In a summit meeting marked by red carpets, handshakes and military flyovers, President Vladimir Putin made his first trip to the United States in a decade and was greeted warmly by President Donald Trump.

The highly anticipated summit ended without a breakthrough. Afterwards, Trump said Ukraine and Russia should proceed straight to seeking a full peace deal instead of a cease-fire.

The documents reportedly included plans for a canceled luncheon, seating charts, a gift presentation and phone numbers for U.S. and Russian officials.

Lawmakers retreated to their partisan corners in response to the Trump-Putin summit in Alaska, with Republicans praising the president and Democrats arguing he was too cozy with Putin.
