The fact that Trump has taken Loomer into his fold as an ad hoc adviser is proof of how central racism and xenophobia are to his presidential bid.

Donald Trump allies are worried that the former president’s ties to right-wing activist Laura Loomer could cost him votes in key battleground states. Hallie Jackson, Jonathan Martin, Marc Short and Symone Sanders- Townsend join the Meet the Press roundtable to discuss.

Laura Loomer, a right-wing activist who posted last year that 9/11 was an “inside job,” joined Republican presidential nominee Donald Trump in New York and Pennsylvania on Wednesday as he commemorated the anniversary of the attacks.
