WASHINGTON — In the latest sign of the Trump administration’s outreach to religious conservatives ahead of a critical midterm election, Vice President Mike Pence told a large gathering of pastors Wednesday that the White House would continue to fight for evangelical priorities. He appealed for the community’s continued support, even as his appearance led to complaints that a religious event was being used for political gain.

“This is a pivotal year in the life of our nation,” Mr. Pence told the annual meeting of the Southern Baptist Convention, where nearly 10,000 evangelical pastors gathered in Dallas. “Be assured of this, President Trump and I are going to continue to fight for what we know is right.”

Mr. Pence recited a list of Trump administration actions that appealed to the conservative evangelical community, which constitutes one of the president’s biggest blocs of supporters. Among the accomplishments he cited were the nomination of Judge Neil Gorsuch to the Supreme Court; advancing anti-abortion priorities across the government; opening an American embassy in Jerusalem; passing tax reform; and freeing Christian hostages from North Korea.

“This progress,” Mr. Pence said, “is the result of the support of men and women like so many of you, who supported our president not only in 2016 but every day since.”
