Mark Teixeira enjoyed plenty of success at the highest level of baseball, following which he has forayed into politics.On Monday's edition of "Rob Schmitt Tonight" on NewsMax, Teixeira, who retired in 2016, commended Donald Trump's "American-first" policies, while criticizing former President Joe Biden's governance."The last four years, I really started getting serious, because we were close to losing our country," Teixeira said. "You look at open borders, you look at dangerous streets, you look at a Democratic Party that is pushing us towards socialism. I, for one, don't want to live in that type of country, and I (don't) want my kids and my grand-kids to live in that type of country."So, it takes American-first conservative policies to bring our country back, and that's exactly what President Trump is doing, and I hope I can join his team to get America back to where we belong, which is prosperous, free and safe."Teixeira made his big league debut in April 2003 and represented some of the sport's biggest franchises, such as the Texas Rangers, Atlanta Braves, LA Angels and New York Yankees in a career that spanned 13 years. His trophy cabinet includes a World Series ring, three All-Star selections, five Gold Gloves and three Silver Slugger awards."I'm ready to help President Trump's America First agenda" - Mark Teixeira has been a staunch supporter of Donald Trump since he announced his congressional bidBack in August, Mark Teixeira announced his plans to run for Congress in Texas as a Republican for the 21st Congressional District.
