Sen. Jeff Sessions, the staunchest supporter of Donald Trump in Congress, told delegates at the Republican National Convention that Trump would stop unfavorable trade agreements and curb illegal immigration in defense of the middle class, which has suffered under President Obama.

“Bad trade deals close factories, and end high paying jobs,” Sessions, R-Ala., said. “Excess immigration floods the labor market, reducing jobs and wages. Improper vetting places our nation at risk of terrorism. Americans want help now. This election will make it happen.”
