evidence: Biden said this week he was "working" on Ukraine’s request as US Secretary of State Antony Blinken and British Foreign Secretary David Lammy made a rare joint visit to the Ukrainian capital, Kyiv, where they announced $1.5bn in additional aid. Blinken wrapped up a three-nation, Ukraine-focused European tour in Poland on Thursday after hearing repeated appeals from Ukrainian officials to use Western-supplied weaponry for long-range strikes inside Russia. "As what Russia’s doing has changed, as the battlefield has changed, we’ve adapted," Blinken said at a news conference in Warsaw.
