WASHINGTON - US President Donald Trump on Sunday announced his support for Republican Governor Matt Bevin of Kentucky ahead of the state's gubernatorial election.

In a tweet, Trump encouraged Kentucky resident to vote for Bevin, which he called a "great governor".

The president also said he wants the vote to "send a strong signal" to House Speaker Nancy Pelosi, likely pointing to a Democratic-led impeachment inquiry into him.

According to the White House, Trump will hold a "Keep America Great" rally at Rupp Arena in Kentucky's Lexington on Monday evening, the eve of Tuesday's gubernatorial election.

Bevin, first elected as governor of Kentucky in 2015, faces Kentucky Attorney General Andy Beshear, a Democrat and son of former Kentucky Governor Steve Beshear, in this year's race.

A poll conducted by Mason-Dixon Polling & Strategy last month found Bevin and Beshear tied, each with 46 percent support from Kentucky voters.

Trump won Kentucky, a red state, by some 30 percentage points in the 2016 presidential election.

Besides Kentucky, Mississippi also will hold a gubernatorial election on Tuesday.

Trump held a rally in Mississippi on Friday to advocate for Lieutenant Governor of Mississippi Tate Reeves' campaign.
