Sen. Dean Heller on Friday signaled that friction with President Trump and his allies wouldn’t chase him out Congress, as the Nevada Republican unveiled his first advertisement of the 2018 campaign.

In contrast to Republican Sens. Jeff Flake of Arizona and Bob Corker of Tennessee, who chose retirement over another term, Heller has been committed to fighting through tough primary and general election campaigns to win his second full term. That bid is set to begin in earnest on Monday with a sustained statewide television and targeted digital advertising that highlights his support for tax reform and Trump’s judicial nominees.
