NEW YORK (CBS/AP) — Former Secretary of State Hillary Clinton is joining the chorus of voices criticizing President Trump’s summit in Helsinki with Vladimir Putin.

Clinton spoke at New York’s OZY Fest on Saturday and addressed Republican President Donald Trump’s encounter with Russian President Vladimir Putin in Helsinki, amid special counsel Robert Mueller’s warning that Russian intelligence services have active “interference operations” in U.S. politics.

During a discussion about “Politics Of The Moment”, she told crowds that she still doesn’t understand why President Trump wants to be friends with Putin.

She was interviewed by Laurene Powell Jobs, founder of the Emerson Collective, a nonprofit advocate of liberal causes that led the event.

“It’s really distressing and alarming,” Clinton said. “It should concern every American of any political party because this was a direct attack on our democracy.”

Clinton, who lost to Trump in the 2016 election, said “It’s fair to say it was a broad and unfortunately successful attack on our electoral system.”

She said the United States has four main adversaries: Russia, China, NorthKorea and Iran.

“If anyone gets away with the attack Russia did, it empowers them all to keep probing.”

As for the Helsinki meeting, “now we have Putin telling the world what was decided,” she said, while “we’re hearing crickets from the White House; nothing has been put out that contradicts or replaces Putin’s agenda.”

Clinton described the Russian leader as a “very aggressive guy,” and said she believes he “wants to dominate his neighborhood again.”

Clinton concluded: “We are still very vulnerable.”

Hillary Clinton also is offering a helping hand to immigrants looking to reunite with their families: She says she’ll help organize transportation they might not be able to afford.

“I’m going to be tweeting about this in the days to come, but if any of you work for an airline please direct message me because these families will need vouchers and discounted tickets to be reunited over these thousands of miles,” she told a crowd cheering her Saturday in Central Park when she took the stage as part of a star-studded summer festival of conversation, music and food.

Immigrants separated from their children after crossing the U.S. border illegally was only one topic addressed by the former Democratic presidential candidate, secretary of state and U.S. senator from New York.
