US national security advisor 'confident' Ukraine will get more military aid

White House National Security Advisor Jake Sullivan has expressed confidence that Congress will approve more aid for Ukraine to fend off Russian aggression.

Sullivan spoke to reporters in the Ukrainian capital Kyiv on Wednesday after meeting Andriy Yermak, the head of the office of the President of Ukraine.

Some Republicans in Congress are reluctant to provide additional military support for Ukraine and have blocked the emergency funding bill submitted by President Joe Biden's administration.

Sullivan reassured Ukrainians that they will get the aid. He said, "Among members of Congress and among the American people, there continues to be a deep and strong reservoir of support for what you are doing."

He added, "We're working with the House to pass. But from our perspective, we are confident we will get this done."

Sullivan was expected to pledge continued support for Ukraine in his meeting with President Volodymyr Zelenskyy.

Yermak said that Ukraine has already signed bilateral security agreements with nearly 40 countries, and is preparing to sign one with the United States. He predicted the accord would be "historic."
