The Nevada Republican Party was expected to hold a vote on possibly changing its rules to allow a bypass of its presidential nominating caucuses in 2020 and endorse Pres. Trump outright.
In April, former Massachusetts Governor Bill Weld became the first person to challenge Mr Trump.
Brad Parscale campaign manager for Trump's 2020 reelection campaign.
McKissick issued a statement Sunday calling Sanford's attempt to unseat Trump a "vanity project", WCSC reported.
Those numbers would suggest that, like other Trump challengers, Sanford has lower odds of actually defeating the president than of successfully criticizing him in a way that could affect the general election.
Asked if the president's Monday night visit on Bishop's behalf would push the Republican over the finish line, O'Callaghan simply replied: "Only time will tell". "It was, but then he ran for Congress and won, only to lose his re-elect [sic] after I Tweeted my endorsement, on Election Day, for his opponent", Trump said on Twitter.
"I don't need someone to take a room overnight at a hotel", he said. Sanford addressed the president's critique after he announced his candidacy.
But Trump campaign communications director Tim Murtaugh said that "these are decisions made entirely by state parties, and there are volumes of historical precedents to support them".

Sanford, who lost a 2018 House Republican primary as the incumbent after criticizing Trump for lying and bullying, points out that the current anti-immigrant, trade-war-embracing administration has stretched far from the GOP's roots as an inclusive, small-government party. State Rep. Katie Arrington repeatedly aired ads featuring Sanford's on-air critiques of Trump and attached the "Never Trump" moniker to Sanford, a condemnation in a state that Trump carried by double digits in 2016.
Sanford declared his long-shot presidential bid Sunday morning in an interview with Fox News' Chris Wallace. "It's something I've apologized extensively for".
But Weld, Sanford and Walsh could mount the strongest opposition to a sitting president in a primary since 1992, or even 1980.
"What's cancerous here is in an open political system, there has to be some measure of objective truth".
Sanford was governor of SC from 2003 to 2011, and served two separate stints in the House of Representatives, but lost a party primary in 2018. He returned to politics a couple of years later and won a special election to his old U.S. House seat in 2013, holding on twice more.
The measure was drafted in response to a state law signed by Democratic Gov. Gavin Newsom in July that requires presidential candidates to release their tax returns, a move aimed squarely at the Republican president.
In 2018, Sanford found himself in the crosshairs of the U.S. president, as he sought re-election to the House of Representatives. Dan Bishop (R), who is running against McCready in North Carolina's 9th congressional district, Trump blasted the state's sanctuary city policies that have resulted in almost 500 criminal illegal aliens being released from police custody since October 2018.
"It's not just debt and spending, which is, again, my primary focus given the fact that we're walking our way toward the most significant financial storm, I believe, in our country since the Great Depression", Sanford said.
