President Donald Trump's midterm campaign blitz arrives in Georgia on Friday for a rally with top Republican candidates in a state that has long been the epicenter of the president's false claims about election fraud.

The Democrat faces more than $158 million in outside spending by Republican leadership and the world's richest man, Elon Musk.

Sen. Susan Collins, R-Maine, and Democratic challenger Troy Jackson will meet on the debate stage Thursday in one of the nation's most closely watched races during this midterm election cycle.
