Washington Capitals say Alex Ovechkin was asked to film a campaign ad for United Russia, the pro-Putin party, while back home this summer.

The team said he was asked, but would not say whether he accepted.

News reports have described the ad as a political endorsement.

The Washington Post and The Guardian report that the NHL star is featured in the ad.

ESPN picked up the team's statement.

Ovechkin has stayed silent publicly.

The request came during his trip in Russia this summer.

The ad is getting attention because United Russia backs President Vladimir Putin.

No further details have been given by the Capitals.
