Midterm campaign updates: GOP's Cheney endorses Ohio Democrat Tim Ryan for Senate

Arizona's Libertarian Senate candidate Marc Victor dropped out of the race on Tuesday, putting his support behind Blake Masters, the Republican nominee.

His move, made a week ahead of Election Day, gives Trump-backed Masters a further boost as Victor's candidacy was forecasted to split off some of the Republican vote in the race to unseat incumbent Democrat Sen. Mark Kelly.

Victor told ABC News in a written statement Tuesday that Blake Masters approached him, agreeing to the Libertarian's offer to both his opponents on "why it was in the interests of freedom, peace, and civility for me to step down and endorse either of them." Their taped conversation "impressed" the Libertarian, Victor said, prompting him to drop out.

"I publicly offered to meet with either Mark Kelly or Blake Masters to have an unscripted discussion about why it was in the interests of freedom, peace, and civility for me to step down and endorse either of them," Victor told ABC News.

"Blake Masters availed himself of that opportunity yesterday, and we had a public conversation where I asked him whatever I wanted. I was impressed with Blake Masters and his commitment to being a Live and Let Live Senator from Arizona," Victor told ABC.

Masters responded to the new support in a campaign press release.

"Marc Victor joins a growing list of Arizonans from across the political spectrum who are fed up with open borders, big government corruption, and rising crime. We are building a broad coalition to defeat the worst Senator in America. This is another major boost of momentum as we consolidate our support against the extreme and radical policies of Mark Kelly and Joe Biden. Live and Let Live," Masters said.

Victor will still be on the ballot, but any votes cast for him will not be tabulated, according to a spokesperson at the secretary of state's office.

Amid post-stroke challenges that were on full display in a debate Tuesday night, John Fetterman is still running for the U.S. Senate out of “love of my state” and “love of my nation,” the Pennsylvania Democrat said on Thursday in his first interview since the debate.

“I think the direction that we could go in if we don’t have -- step up and fight for that, as well too,” Fetterman told Javier Palomarez, president of the United States Hispanic Business Council, which hosted a pre-planned virtual town hall with the candidate.

“If anyone has any question, you know, I always show up, I always lean in, and I always make sure to,” Fetterman told Palomarez, alluding to the scrutiny over his health both before and after the debate, when his auditory and language issues caused him to repeatedly struggle to answer questions on stage.

Over the course of Thursday’s roughly 35-minute interview, which took place on Zoom with closed captioning, Fetterman was asked about policy issues that might affect Hispanic business owners rather than about his debate performance.

Fetterman was asked to clarify his stance on hydraulic fracking, an issue about which he has made contradicting statements.

“I absolutely would support fracking, and I have,” he told Palomarez when asked about previously calling the industry “a stain on Pennsylvania.”

Fetterman said his previous opposition to fracking was borne from environmental concerns but that the war in Ukraine makes it an essential part of the state’s economy.

The United States Hispanic Business Council will host a similar town hall with Fetterman’s opponent, Republican Mehmet Oz, on Friday afternoon.

The conservative Club for Growth is putting out a new ad looking to boost Sen. Mike Lee, R-Utah, as he faces a tougher-than-anticipated challenge from independent Evan McMullin.

The video, backed by an $800,000 reservation, will begin airing statewide Wednesday through Election Day. The 30-second clip features former Gov. Jon Huntsman, who served one term and was later the U.S. ambassador to Russia during the Trump administration.

"There's a lot of noise out there right now, so let me tell you what I know about Mike Lee. I've worked with Mike since I was governor, and I know his heart. He has the unshakeable integrity that's all too scarce in politics. You might not always agree with Mike. I don't. But we can all agree that principled leadership and fidelity to the Constitution are paramount in difficult times. Let's send Mike Lee back to the Senate," Huntsman says in the ad.

The late buy suggests 11th-hour handwringing by some of Lee's allies over McMullin's bid.

Lee recently went on Fox News to plead with Sen. Mitt Romney, R-Utah, for his endorsement, and the FiveThirtyEight polling average only has Lee up by about 8 points after he won reelection in 2016 by more than 40.

McMullin has centered his challenge around Lee's communications discussing methods to challenge the 2020 election results after the race was over, accusing Lee of shedding his label as a "constitutional conservative." Lee notes he did not ultimately reject to certifying the Electoral College results.

He and his allies have accused McMullin -- who previously worked as a Republican congressional aide and then ran for president in 2016 as an independent -- of now being a closet Democrat, noting that the state Democratic Party endorsed him and did not run a candidate of its own. McMullin, though, has said he wouldn't caucus with either party in the Senate.

The newest John Fetterman ads feature words of support from former President Barack Obama, the latest high-profile surrogate to involve himself in Pennsylvania's crucial Senate race.

"When the fate of our democracy and a women's right to choose are on the line, I know John will fight for Pennsylvanians," he says in both ads.

Notably, in the radio ad, Obama touts Fetterman's service on the state Board of Pardons, which opponent Dr. Mehmet Oz attacks repeatedly by accusing Fetterman of endangering Pennsylvanians by voting to commute the sentences of some convicted murderers.

"As Lieutenant Governor, John chairs the Board of Pardons and has helped people who were wrongfully convicted," Obama says.

In a statement, Fetterman said, "I am deeply grateful for President Obama's support in this race. I was proud to be one of the only elected officials in western Pennsylvania to endorse President Obama in the 2008 presidential primary, and it is truly an honor for him to get behind our campaign and cut ads for us across the commonwealth."

While the campaign noted in a press release that the ads will appear "across Pennsylvania" in the coming weeks, the radio hits began airing in the Philadelphia market this week.
