On Wednesday, Sen. Bob Corker withdrew himself from consideration as Donald Trump’s running mate. However he did float an alternative person for the position: the presumptive nominee’s daughter.

During an interview on Capitol Hill Corker told CNN’s Manu Raju, “His best running mate, by the way, would be Ivanka.”

Although Corker knew this option “would not pass muster,” he found Donald Trump’s daughter to be “most impressive.”

The Tennessee senator said that on Tuesday, as he campaigned with Trump in Raleigh, North Carolina, he met with Ivanka Trump and Kushner, who have both played large roles in the campaign.

Ivanka Trump has played a pivotal role in convincing her father to fire campaign manager Corey Lewandowski. The businesswoman and mother of three has also been an outspoken surrogate for her father — and has risen to his defense during moments of controversy.

In October Ivanka told CNN’s Poppy Harlow that she thinks her father would be “amazing” for women. She said, “I don’t think that he’s gender-targeted at all. I wouldn’t be the person I am today, I wouldn’t be a high-level executive within his organization, if he felt that way.”

Ivanka’s husband Jared Kushner has also played an increasingly large role in Trump’s campaign. He has provided assistance with everything from fundraising to speech writing to helping select a vice presidential running mate.

While it may not be likely that Ivanka will be selected as her father’s running mate, Ivanka Trump would just pass the constitutional age of 35 required to hold the position. Her birthday is in October, less than three months before inauguration.
