Biden told top national security officials that leaks about intelligence sharing with Ukrainians must stop

Last week, after the White House denied providing intelligence directly to the Ukrainians “with the intent to kill Russian generals,” Biden spoke separately with Defense Secretary Austin, CIA Director Burns, and Director of National Intelligence Avril Haynes. One of the officials said he told them it was not helpful to publish information about what the United States shares with Ukrainian forces fighting the Russian invasion, and emphasized that leaks about this information must stop.

US officials have been upfront about sharing intelligence with the Ukrainians, but they also said there is a line in what is being shared with them. A spokesman for the National Security Council said last week that in addition to sending weapons to the battlefield, officials provided intelligence “to help the Ukrainians defend their country.”

Administration officials have previously insisted that there are clear limits on the intelligence it shares with Ukraine, including a prohibition on providing accurate intelligence targeting senior Russian leaders by name. These limits are part of the White House’s efforts to avoid crossing a line that Moscow might view as too escalating.

But the intelligence-sharing effort has proven fruitful. So far, the information has contributed to the successful strikes against top Russian commanders and the Russian Navy’s ship Moskva, sources familiar with the intelligence-sharing previously told CNN.

To date, Russia has not taken any known direct action against the United States or NATO in response to the ongoing military and intelligence support.

US officials have been left to speculate about why Moscow is backing down, particularly when it comes to cyberattacks, which the US had warned before the war that Russia might use as punishment for US assistance. Nor did Russia move to strike Kyiv during visits by a host of senior US leaders, from House Speaker Nancy Pelosi to Secretary of State Anthony Blinken.

Nor did the country attempt to strike at arms shipments flowing through Poland, a NATO country. Russia only recently began targeting railways inside Ukraine that are believed to be carrying Western weapons for combat.

In addition to sharing intelligence, the United States has also provided billions of dollars in aid to Ukraine in its war against Russia.

last week, Biden announces $150 million package This includes 25,000 rounds of 155mm artillery, anti-artillery radars, jamming equipment, field equipment and spare parts, according to a White House official.

Biden proposed a new $33 billion aid package for Ukraine, which he sent to Congress last month. The United States has made clear it intends to provide long-term support to Ukraine, and last week’s proposed package was more than double the $13.6 billion injection of military and humanitarian aid approved by Congress last month.
