Trump is sending up to 15,000 US troops to the border to stave off a caravan of migrants slowly making its way through southern Mexico, hundreds of miles from the border. Trump has also announced plans to try to end the constitutionally protected right of birthright citizenship for all children born in the US.

SENATE STAKES

Republicans predicted that they would pad their two-seat Senate majority even though the party of a first-term president typically struggles in midterm elections. Democrats are defending 10 Senate seats in states Trump carried in 2016.

Sen. Thom Tillis, R-N.C., said Republicans would not only "hold the majority — I believe we're going to add to it." Republican National Committee Chairwoman Ronna McDaniel pointed to the recent October jobs report as evidence Republicans are delivering.

"We have a record of results and the Democrats have a record of resistance and obstruction," she said, arguing that voters would return Republicans to the majority.

Sen. Mark Warner, D-Va., said that even if voters are motivated by a strong economy, "many people realize we need a check on this president." And Sen. Chris Van Hollen, D-Md., said the party still has a "very narrow path" to a Senate majority despite facing the toughest Senate political map in 60 years.
