Trump is heading to Texas for the fourth time since Labor Day to campaign.
There is just one week until the high-stakes midterm elections on Tuesday, Nov. 3.
There are several key House and Senate races that could determine the balance of power in Congress as well as significant races for governor around the country. The elections could ultimately determine how effective President Donald Trump's agenda is in the back half of his second term.
