 President Biden hosting a NATO summit starting Tuesday in Washington, where ABC's Perry Russom is. According to a senior Biden administration official, there will be a strong demonstration of support for Ukraine, reaffirming Ukraine's future is in NATO, with this being a part of the country's bridge to NATO. That is exactly what Russia's President Putin does not want to hear. Plus, the U.S. is expected to announce new steps to strengthen Ukraine's air defenses and military capabilities, with more financial and political support from NATO members.
