NEW YORK -- Jose Canseco is ready to take a swing at politics.

The former major league slugger has made his pitch for a big job at the White House, tweeting Wednesday to President Donald Trump: "u need a bash brother for Chief if (sic) Staff."

Hey little buddy @realDonaldTrump u need a bash brother for Chief if Staff. Got a secret reorg plan already. Also worried about you looking more like a Twinkie everyday. I will buff you up daily workouts. DM me. #yeswecanseco — Jose Canseco (@JoseCanseco) December 13, 2018

Canseco told his "little buddy" he has "a secret reorg plan already." He suggested Trump send him a direct message and signed off #yeswecanseco.

This wasn't the first time Canseco volunteered to serve in Trump's administration. On Oct. 9, after Nikki Haley announced that she was stepping down as U.S. ambassador to the United Nations, Canseco said he'd be up for the job.

Hey little buddy @realDonaldTrump I am interested in United Nations leadership .dm me for ideas and confidential 90 day plan #readynow — Jose Canseco (@JoseCanseco) October 9, 2018

The outspoken Canseco knows his way around Washington. He testified on Capitol Hill before Congress during its 2005 hearings into the use of steroids in baseball.

Canseco hit 462 home runs during 17 seasons in the majors. He played for seven teams from 1985 to 2001 and was the 1988 American League MVP with Oakland.

Trump's decision on a replacement for departing chief of staff John Kelly is expected by the end of the year.
