Ukrainian President Volodymyr Zelenskyy said Saturday that the tanks Poland agreed to give Ukraine are already in the country, including the Leopards.

"Poland has fulfilled everything it declared about tanks," Zelenskyy said during his nightly address, adding that there is also an agreement on 200 Rosomak armored personnel carriers and "self-propelled mortars, additional missiles, MiGs."

American Wall Street Journal reporter Evan Gershkovich has now been formally charged with espionage, according to Russian state media. The move by Russia comes as a campaign to free him swells, with Senate leaders issuing a bipartisan demand to free him.

The formal charging shows Russia is pressing ahead with putting the journalist on trial, despite a growing outcry that has seen dozens of global media outlets demand his release.

Senate Majority Leader Chuck Schumer and Minority Leader Mitch McConnell on Friday issued an unusual bipartisan statement calling for Gershkovich’s immediate release, saying "journalism is not a crime."

They also demanded Russia allow consular access to Gershkovich, who U.S. diplomats have still not been allowed to visit 10 days since his arrest, in violation of international rules.

The U.S.’s National Press Club has also now awarded Gershkovich its highest honor for press freedom, praising him for his brave commitment to reporting on Russia despite the risks.

The Pentagon is investigating the reported leak of classified U.S. and NATO documents posted on Twitter and Telegram, a spokesperson said.

The New York Times first reported the investigation.

"We are aware of the reports of social media posts, and the Department is reviewing the matter," Pentagon Deputy Press Secretary Sabrina Singh said in a statement provided to ABC News.

The war plans provided statistics on Ukrainian troop and casualty numbers as well as information about weapons deliveries and Ukrainian troop schedules, the New York Times reported.

At a press conference following a bilateral NATO meeting in Brussels, Secretary of State Antony Blinken told reporters the U.S. is going through a formal process to determine whether it will designate Wall Street Journal reporter Evan Gershkovich as wrongfully detained in Russia, but said he has no doubt that is the case.

"In Evan’s case, we are working through the determination on wrongful detention, and there's a process to do that, and it is something that we are working through very deliberately but expeditiously as well," Blinken answered a WSJ reporter who had asked about the determination.

"I'll let that process play out. In my own mind, there's no doubt that he's being wrongfully detained by Russia, which is exactly what I said to Foreign Minister [Sergey] Lavrov when I spoke to him over the weekend and insisted that Evan be released immediately," Blinken added.

Blinken said he expected the formal process to be "completed soon."

Ukrainian forces have killed 225 Russian fighters and injured another 306 in the past 24 hours in the Bakhmut area, according to Serhiy Cherevaty, the spokesman for the Eastern Group of Forces of the Ukraine army.

Russia and Ukraine have been locked in a brutal battle for the city in eastern Ukraine for months, with both sides seeing high rates of casualties.

Cherevaty said that in the last day, the occupiers in the area of Bakhmut and nearby villages -- including Orikhovo-Vasylivka, Bohdanivka and Ivanivskoho -- tried to attack Ukrainian positions 42 times. There were 24 combat clashes in the Bakhmut area alone.

In total, in the Bakhmut direction, the occupiers shelled Ukrainian positions 256 times with various types of artillery and multiple launch rocket systems, Cherevaty said. Of them, 53 shellings were in the area of Bakhmut itself.
