Grynkewich has been playing a lead role in orchestrating new military aid for Ukraine, including an initial aid package now totaling $1.5 billion.
Under the plan endorsed by Trump, five European allies -- the Netherlands, Norway, Denmark, Sweden and Germany -- have agreed to purchase air defense capabilities, missiles, artillery and ammunition from U.S. companies. The weapons would then be provided to Ukraine. A senior NATO military official said to expect "further significant announcements from other allies soon."
Officials said Grynkewich and Caine, who is chairman of the Joint Chiefs, will be on hand at the summit to provide Hegseth and the president military advice.
