WASHINGTON — President Donald Trump said Tuesday that he’s not worried Moscow will meddle in the upcoming midterm elections because the U.S. will take steps to prevent it. “Whatever they do, we’ll counteract it very strongly,” Trump said.

Top intelligence officials, however, have said that so far the U.S. has responded weakly to Russia’s disinformation campaign to sow discord in America and raise doubts about the integrity of the presidential election.

Trump, who has refrained from pointing a finger at Moscow, acknowledged that Russia interfered in the presidential election, but said it had no impact on the U.S. vote tally. “Certainly there was meddling and probably there was meddling from other countries and maybe other individuals,” he said at a news conference with Swedish Prime Minister Stefan Löfven.

Trump said his administration is conducting a study and will have strong suggestions on protecting the midterms and beyond.

“You have to be very vigilant,” Trump said. “And one of the things we’re learning it is always good — it’s old-fashioned — but it’s always good to have a paper backup system of voting. It’s called paper. Not highly complex computers. Paper. A lot of states are going to a paper backup.”

Adm. Mike Rogers, the outgoing director of both the U.S. Cyber Command and National Security Agency, said the U.S. response to Russia has not been strong enough to change Moscow’s activities.

Rogers told Congress last week that he’s taken steps to respond to the threat, but that neither Trump nor Defense Secretary James Mattis has granted him any additional authorities to counter Russian efforts.

“I believe that President (Vladimir) Putin has clearly come to the conclusion that there’s little price to pay and that therefore, ‘I can continue this activity,”’ Rogers said. “Clearly what we have done hasn’t been enough.”

In January, the Trump administration was harshly criticized for not imposing new sanctions when a list of 114 Russian politicians and 96 oligarchs was released to comply with a law Congress passed to punish Moscow for interfering in the 2016 U.S. election.
