Trump is campaigning with former House Speaker Newt Gingrich today in Cincinnati; New Jersey governor Chris Christie is still under consideration

Tennessee senator Bob Corker is no longer in the running to be Donald Trump's vice presidential running mate, saying on Wednesday that the job is too 'highly political' for a policy-oriented statesman like him – but should go to Trump's eldest daughter.

"His best running mate by the way would be Ivanka. She’s most impressive,' Corker told CNN.

'There are people far more suited for being a candidate for vice president, and I think I’m far more suited for other types of things,' Corker had told The Washington Post, while praising Trump as a strong candidate.

Corker told CNN that he would consider serving a Trump administration as secretary of state, and will likely accept a speaking slot at the Republican National Convention. Trump said Wednesday that the list of speakers would be unveiled Thursday.

Tennessee Republican Bob Corker, 63, met with Donald Trump on Tuesday and decided before appearing with him at a North Carolina rally that he doesn't want to be Vice President of the United States

Corker told the Post that he spoke with Trump aboard the billionaire's personal Boeing 757 plane on Tuesday, saying he's not cut out for making rousing speeches or becoming the real estate tycoon's election-year attack dog.

The two were en route to a rally in Raleigh, North Carolina where Corker spoke for barely a minute about Trump's family and employees but didn't delve into either government policy or presidential politics.

'It's a highly political job, and that’s not who I am,' Corker told the Post. 'We had a very open conversation about that, and actually, we have been very candid about it from the very beginning of our meetings.'

'I left there feeling very good about him as a person but also realized that at age 63, I know the things I’m good at doing and knowing what a candidate for vice president has to do. It's just not the right thing for me, and I don’t think it’s the right thing for them.'

'So, I'm going to move on,' Corker said. 'I am very positive about him as a person. It was incredible to be with him in Raleigh and see the way people react to him. They’re so excited, and I truly believe he has such an opportunity ahead.'

Corker was touted as a seasoned foreign policy voice who could help sell Trump's vow to crush the ISIS terror army, take on China, and roll back illegal immigration.

As chairman of the Senate Foreign Relations Committee, he had submitted formal vetting materials to the Trump campaign, NBC News reported.

Corker had private meetings with Trump and campaign staff in New York Tuesday before the campaign trip to North Carolina.

Like Trump, Corker made big bucks in real estate.

But he's also a soft-spoken, folksy voice on foreign policy, even as he has attacked the Obama administration over its Iran policy and other matters.

His selection might have soothed members of the GOP foreign policy establishment, some of whom have backed away from Trump and even said they may support Hillary Clinton.

He had joined a list of vice presidential finalists that included former House Speaker New Gingrich, who appears with Trump at a campaign rally in Cincinnati today.

New Jersey governor Chris Christie is also being vetted, although Christie, who is advising Trump on a presidential transition, is also mentioned as someone who could play a chief of staff type of role.

Trump met with Indiana Governor Mike Pence, who said nice things about Trump even as he endorsed Ted Cruz shortly before the Indiana primary, on Saturday. Iowa senator Joni Ernst had a meeting with Trump on Monday.

Word of Corker's presence in the final circle of potential running mates came amid reports that Trump will announce his selection next week. The Republican National Convention is set to begin July 18.

Republican senator Tom Cotton of Arkansas, a first-term senator considered a fresh face in the Republican Party, told CNN Wednesday, 'I am not being vetted' for the VP job and said he has 'no reason to believe I’d be selected.'

CNN reported that Republican National Committee Chairman Reince Priebus and campaign chairman Paul Manafort were both in on the meeting with Ernst. A source told the outlet the meeting was to discuss whether Ernst wanted to be vetted for the job.

The New York Post on Tuesday floated the name of Lt. Gen. Michael Flynn, former head of the Defense Intelligence Agency.
