Democrats prepare Ukraine ambush against Trump nominees

• Democrats — and many European leaders — were deeply dismayed by Trump's and Vice President Vance's exchange with Zelensky.
• They were dumbfounded by Trump's conciliatory words for Russian President Vladimir Putin.
• It will also give senators an opportunity to ask officials for details on Trump' pause on military funding for Ukraine.

Driving the news: Matthew Whitaker, Trump's pick to be ambassador to NATO, and Michael Rigas and Christopher Landau, his nominees for the two deputy secretary of state slots, are scheduled to appear before the Senate Foreign Relations Committee on Tuesday morning.

• Trump's nominees are indicating they'll fiercely defend Trump's approach and demand that European allies do more to strengthen NATO.
• "Leadership is not charity. The American people have carried the burden of global security for too long," Whitaker will say in his opening comments, according to remarks Axios obtained.
• "For decades, U.S. taxpayers have funded the lion's share of NATO's defense while too many of our allies have failed to meet even their most basic obligations."

What they're saying: "It is an open question that deserves a clear answer, whether or not this administration and its nominee to be our ambassador to NATO believe in the value of the NATO alliance," Sen. Chris Coons (D-Del.) told Axios.

• "He has told me in a private meeting that he is supportive" of NATO, Sen. Jeanne Shaheen (D-N.H.), the top Democrat on the committee, said of Whitaker.
• "The relationship with NATO, the relationship with Ukraine, the president buddying up to dictator Putin ... all of these are big problems," said Sen. Jeff Merkley (D-Ore.).
