New emails from President Trump’s campaign obtained by The Washington Post show that one staff member on multiple occasions tried to set up meetings between campaign and Russian officials.

The Post in a report published Monday detailed the emails sent by George Papadopoulos, who was a volunteer on Trump’s campaign, from March through September of last year.

Papadopoulos in April told Trump’s campaign manager at the time, Corey Lewandowski, that Russian President Vladimir Putin wanted to “host the Trump team when the time is right.”

Several Trump officials, including Paul Manafort, who served as Trump’s campaign chairman, expressed concern over the proposed meetings. 

Other officials who raised concerns over Papadopoulos’s proposals to meet with with Russian officials include the Trump campaign’s co-chairman, Sam Clovis, and Navy Rear Adm. Charles Kubic.

Papadopoulos also passed on an exchange with the Russian International Affairs Council (RIAC), which conveyed that the Russian foreign ministry was receptive to Trump making a trip to Russia.

An official with the Council confirmed that a discussion about a U.S.-Russia dialogue “informally” occurred.
