National security advisor Michael Waltz says Ukraine should 'tone down' Trump criticism

National Security Advisor Mike Waltz told Fox News that Ukraine needs to "tone down" its criticism of President Donald Trump and should sign an economic deal.

"Why we are getting this pushback and certainly this kind of – as the vice president said, badmouthing in the press -- for all the administration has done in his first term as well and all the United States has done for Ukraine is just unacceptable. They need to tone it down and take a hard look and sign that deal," Waltz said about Ukraine on Thursday.  Greg Norman is a reporter at Fox News Digital.

"There is obviously a lot of frustration here," he added. "Vice President Vance was very frustrated leaving [last week’s] Munich Security Conference. Our Secretary of Treasury who traveled all the way to Kyiv is also frustrated, all on top of the president, obviously, who makes his frustration well known and that is because we presented the Ukrainians really an incredible and historic opportunity to have the United States of America co-invest in Ukraine, invest in its economy, invest in its natural resources, and really become a partner in Ukraine’s future in a way that is sustainable, but also would be I think the best security guarantee they could ever hope for, much more than another pallet of ammunition."
