"While we have some remaining drawdown authority that we can draw on to continue to provide security assistance to Ukraine in the short-term... USAI funding has been suspended, FMF funding has been suspended," Miller stated during a press briefing. "Those are the contracting programs that allow us to contract for Ukraine in the long-term," the spokesman added.
The State Department calls on Congress to replenish both short-term and long-term security assistance funding for Ukraine, Miller said.
At the same time, a US official confirmed to Sputnik on Monday that $5.4 billion remains in available funding for Ukraine amid Russia's special military operation.
The $5.4 billion available allows the United States to send weapons and equipment from its own stockpiles to Ukraine under the presidential drawdown authority.
Moreover, according to the US official, only $1.6 billion remains in funding from the $25.9 billion approved by Congress to replenish US military stocks depleted by Ukraine security assistance packages.
The US official said there are too many variables to speculate how long the remaining Ukraine funds will last.
Media reported earlier, citing Pentagon officials, that the remaining funding for Ukraine should last about six months.
On Saturday, Congress passed a short-term spending bill that did not include additional assistance for Ukraine. However, the shot-term spending bill gives lawmakers until November 17 to consider full-term spending legislation for next year, including more funding for Ukraine.
President Joe Biden recently asked Congress to approve some $24 billion in additional aid for Ukraine in his $40 billion supplemental request.
