The United States is ready to cooperate with European allies on the issue of espionage, White House spokeswoman Karine Jean-Pierre said at a briefing on Tuesday.

“We will work with our European allies and partners to deal with any issues that arise through the appropriate national security channels,” a spokeswoman for the US administration said when asked to comment on media reports that Denmark helped the US wiretap some European leaders.

On Sunday, the German newspaper Süddeutsche Zeitung reported that the National Security Agency, with the help of Denmark, in 2012-2014, monitored some European politicians, including specifically-German Chancellor Angela Merkel, Foreign Minister (current President of Germany) Frank-Walter Steinmeier, and the candidate for Chancellor of Germany from the Social Democratic Party of Germany, Peer Steinbrueck.

“In 2014, the United States conducted an analysis of the issue of surveillance methods abroad, and President Obama issued a presidential directive that significantly changed the approach to this issue,” a White House spokeswoman said.
