A political action committee supporting President Donald Trump has funded a "six-figure" ad campaign praising U.S. Sen. Roger Wicker, who is up for re-election next year.

The ads focus on Wicker's support for the Trump-led tax cuts, a version of which the Senate has passed, with passage of a final version expected this week.

"Hard-working Mississippi families need lower taxes, and Roger Wicker and President Trump are fighting for us," says one ad, titled "Strong Again – Mississippi."

Trump has pledged support for Wicker after former top Trump political adviser Steve Bannon include Wicker on his list of incumbent Republican senators he wants to oust.

Bannon has encouraged state Sen. Chris McDaniel, R-Ellisville, who unsuccessfully challenged U.S. Sen. Thad Cochran in the 2014 GOP primary, to challenge Wicker in next year's primary. McDaniel recently said he would announce a decision on running next month.

"Thank Mississippi Senator Roger Wicker for standing with President Trump," the ad says.

Wicker has embraced Trump's support. It makes him less vulnerable to an anti-establishment challenge from the right in the primary.

The new pro-Wicker ad spot will run on statewide television in a mix of broadcast and cable, and include radio as well. It is funded by the pro-Trump 45Committee.
