Former Sen. Jeff Sessions, R-Ala., billed his trip to the Republican National Convention - where he spoke on behalf of President Trump and met with a Russian ambassador - to his own political campaign, according to campaign finance records.

The findings come after the Trump campaign had said Sessions attended in his capacity as a senator, though he spoke on behalf of Trump and later met with foreign officials. On Thursday, Sessions told reporters at a press conference that he had talked with Russian ambassador Sergey Kislyak on two occasions, one of which was at a diplomacy conference in Cleveland, which he attended while at the GOP convention last July.

Sessions reported making two payments of $1,395 to the Sheraton Cleveland Airport. The campaign also paid $223 to the Westin Hotel in Cleveland. Both were deemed "lodging" expenses, according to the Wall Street Journal.

Three more members of Trump's campaign spoke with Kislyak, according to reports Thursday evening.

Jared Kushner, Trump's son-in-law who is now a White House senior adviser, met with Kislyak at Trump Tower in December, though it's unclear what they discussed, according to the New York Times.

Staffers J.D. Gordon and Carter Page also met with Kislyak at a diplomacy conference last July.

Then-Sen. Jeff Sessions' talked with Kislyak at the same Global Partners in Diplomacy event, as well as in September. A number of Trump campaign associates were in attendance of the July event.
