The Senate confirmed Chris Wright to lead the U.S. Department of Energy on Monday, putting the former oil executive in a key position to help shape President Trump’s energy policies.

Such a scenario would represent a notable degree of ticket-splitting, perpetuating a trend captured by surveys throughout this election cycle. Democratic Senate candidates in a number of swing states, including Arizona and Nevada, have consistently polled ahead of the top of the ticket, especially when President Biden was the party’s standard-bearer. As Ms. Harris’s nomination has made the election more competitive, the gap between her and those down-ballot Democrats has narrowed — but the trend persists in most races in swing states.

Ms. Harris may give remarks about border issues during the visit, according to the people, who insisted on anonymity to discuss a trip that has not yet been made public. The people said final details about exactly where Ms. Harris would visit or what else she might do on the trip have not been decided. The Harris campaign did not immediately provide a comment.

Mr. Wright, the founder and chief executive of Liberty Energy, a fracking firm, was confirmed by a vote of 59 to 38,rpjili com with support from all Republicans present and a smaller number of Democrats. He would be the 17th secretary of energy, a position that was created in 1977.

At his confirmation hearing, Mr. Wright said his top priority was to “unleash” domestic energy production, including liquefied natural gas and nuclear power. He also told Democrats that he believed climate change was a “global challenge that we need to solve” and that he would support the development of renewable energy like wind and solar power.

At the same time, Mr. Wright said he would “work tirelessly” to support Mr. Trump’s “bold” energy agenda. The president has frequently dismissed climate change as a hoax, disparaged wind and solar power and said he wants to expand the use of oil, gas and coal, the burning of which is driving climate change.

The Energy Department plays a central role in developing new energy technologies. The agency oversees a network of 17 national laboratories that conduct cutting-edge research as well as a powerful loan office that has backed dozens of low-carbon energy projects, including battery factories in Ohio and Tennessee and two giant nuclear reactors in Georgia.

Mr. Wright would also oversee approvals of liquefied gas export terminals, which the Biden administration tried to slow, angering industry groups. Mr. Trump has already ordered the Energy Department to restart reviews of proposed export facilities.
