Trump said he would endorse his daughter-in-law, Lara Trump, if she decided to run. He will now likely endorse Michael Whatley in his bid.

Republican National Committee Chairman Michael Whatley is expected to run for the Senate in North Carolina, setting up a marquee race in next year’s midterms, two sources familiar with Whatley’s plans tell CNN.

Whatley previously met with National Republican Senatorial Committee Chairman Tim Scott about a potential Senate run in North Carolina, and the NRSC had been floating Whatley as a possible replacement for Tillis since January, according to a GOP operative. Tillis did not announce his plans to not seek re-election until months later.
