Newt Gingrich will make his first appearance with presumptive GOP nominee Mitt Romney on May 29 in Las Vegas.
NBC News has learned the former House speaker will attend a fundraiser for Romney at Trump Towers in Las Vegas Tuesday evening. Donald Trump will also attend.
The last time Gingrich and Romney were in Nevada together was in early February, amid a bitter fight for the nomination.
Rumors broke just days before the Feb. 4 Nevada caucuses – and were confirmed by several news outlets -- that Trump himself would endorse Gingrich. Hours later, however, the casino mogul endorsed Romney.
A joint public event with the two former competitors may occur next month.
