As stated by the Embassy of Ukraine in the USA on Facebook, the USA’s defense budget for 2019 provides for 250 million dollars’ worth of assistance to Ukraine.
"The U.S. House Committee on Armed Services, a standing committee of the United States House of Representatives introduced the draft proposal for 2019 defense budget. The amount of funds proposed to provide for “security assistance” to Ukraine, including lethal weapons, is 250 million dollars, which is 100 million more than was proposed by the Committee in the current budget year,” the statement reads.
50 million dollars of this amount are slated "solely for the provision of lethal weapons of defensive nature.” The draft bill must agree with the version that will be prepared by the Senate. Both Houses of Congress will vote on it before submitting it to the President for his signature.
At the end of December 2017, Donald Trump signed the draft defense budget for 2018 that provides for 350 million dollars to Ukraine.
