A Dallas fundraiser featuring President Donald Trump has been moved to May 31.

According an invitation obtained by The Dallas Morning News, the joint fundraiser will be sponsored by Trump’s 2020 re-election campaign and the Republican National Committee.

The president had been scheduled to headline the Dallas event on May 14.

“Do to an unavoidable change in President Trump’s schedule, our Trump Victory dinner in Dallas is being rescheduled to Thursday, May 31,” Republican fundraiser Alison McIntosh told invited guests.

No explanation was given for Trump’s “unavoidable change.” He’s entering a critical period in his young administration, including upcoming talks with North Korean leader Kim Jong-un.

Trump was in Dallas Friday for the National Rifle Association Convention, where he gave a sprawling speech in support of gun rights. He also boasted about the accomplishments of his administration, criticized the special investigation into Russia’s involvement in the 2016 election and praised hip-hop artist Kanye West for helping him improve his standing with black voters.

Trump has said Dallas in one of his favorite stops.

For the 2016 presidential campaign, North Texas was instrumental in raising significant campaign cash for Trump. Texas money for a single political action committee led by Dallas businessmen Ray Washburne and Roy Bailey was more than was raised in all for Trump in New York and California combined.

Trump came to Dallas in October for a fundraiser and to participate in a hurricane recovery briefing.
