Manchin, a moderate Democrat, is among those up for reelection next year being targeted by Republicans, who hope to seize on President Trump's wave of support in West Virginia in the November election.

The ad, put out by the Senate Leadership Fund, splices together a slew of clips of Manchin voicing support for former Democratic presidential nominee Hillary ClintonHillary Diane Rodham ClintonWoman behind pro-Trump Facebook page denies being influenced by Russians Trump: CNN, MSNBC 'got scammed' into covering Russian-organized rally Pennsylvania Democrats set to win big with new district map MORE during the 2016 campaign.


“Don’t be fooled,” a banner at the end of the ad reads, apparently casting doubt on Manchin’s willingness to work with Trump after he was elected.

Manchin has been among the Democratic senators most willing to cooperate with Trump following the bitter campaign, voting to confirm all but four of Trump’s Cabinet nominees that have gone before the Senate.
