Republican presidential nominee Donald Trump is returning to Texas next month to raise money for his campaign.

Trump will attend a fundraiser on the evening of Aug. 23 in Austin, according to Mica Mosbacher, a former finance co-chair of the Republican National Committee who is aiding Trump’s efforts in Texas. 

“Republican donors in Texas seem to be firmly behind the nominee,” said Mosbacher, who previously helped with fundraising for Ted Cruz‘s presidential campaign. “He’s growing the donor base, which tells me he’s growing the party.” 

Trump’s last visit to Texas happened over two days in June, when he held fundraisers in Dallas, San Antonio and Houston, as well as rallies in Dallas and The Woodlands. His son, Donald Trump Jr., was in Dallas and Houston on Monday for fundraisers. 

The August fundraiser will likely be Trump’s first trip to Texas since he officially became the Republican nominee last week at the GOP national convention in Cleveland.
