These contenders for secretary of state did not donate to Trump's campaign

None of President-elect Donald Trump's potential picks for secretary of state actually donated money to his campaign, according to a recent Center for Responsive Politics report.

Former New York City Mayor Rudy Giuliani, former ambassador John Bolton and former House Speaker Newt Gingrich all declined to contribute — at least directly — to Trump's campaign, the report found.

Rudy Giuliani

An ardent and outspoken supporter of Trump, the former mayor did not donate any money to his campaign, according to OpenSecrets. Giuliani did, however, donate to Sen. John McCain (R-Ariz.), Rep. Dan Donovan (R-N.Y.) and House Speaker Paul Ryan (R-Wis.).

Giuliani also donated nearly $10,000 to the National Republican Congressional Committee in 2016.

John Bolton

According to Open Secrets, Bolton donated only to his own John Bolton PAC and the John Bolton Super PAC.

In turn, the PAC donated $590,000 only to Republican congressional candidates. The super PAC spent nearly $2.6 million on GOP candidates in Nevada, New Hampshire and North Carolina.

As the Center for Responsive Politics report pointed out, Democrats succeeded in both Nevada and New Hampshire.

Sen. Bob Corker

Neither the Tennessee lawmaker nor his wife contributed to Trump's campaign, according to the report. In fact, the report states, neither have donated to a presidential campaign since George W. Bush and George H. W. Bush.

The report did note that Corker's PAC, the Rock City PAC, has raised more than $36.4 million. Approximately $5.3 million came from Corker himself.

The PAC donated to the several state party committees as well as $235,000 to Republican Senate candidates this cycle.

Newt Gingrich

Like Giuliani, Gingrich is an ardent and longtime supporter of Trump. Gingrich said Thursday that he would not hold a Cabinet position in Trump's administration, but even still, he did not donate to Trump's campaign.

According to the OpenSecrets report, Gingrich maxed out his campaign donations both in the past two presidential cycles — for himself and McCain — but did not do so this year.

South Carolina Gov. Nikki Haley and 2012 GOP presidential nominee Mitt Romney have also been floated as potential secretaries of state under Trump's administration. Haley met with Trump earlier this week, and the former Massachusetts governor will meet with the president-elect over the weekend.

The Open Secrets report did not include either in its report.
