President Donald Trump rehashed longstanding grievances over the Russia investigation that shadowed much of his first term, lashing out Tuesday following a new report from his intelligence director aimed at casting doubt on long-established findings about Moscow's interference in the 2016 election.

Russia unleashed one of its largest aerial assaults on Ukraine in recent months, hours before Britain and Germany chaired a meeting Monday to discuss President Trump’s plans for NATO allies to provide Ukraine with weapons.

The British defense chief is expected to urge Ukraine’s Western partners at the meeting to launch a “50-day drive” to get Kyiv the weapons it needs to fight Russia’s bigger army.
