WASHINGTON (AP) -- Donald Trump is wasting precious time.
By now, Republican Party critics argue, the party's presumptive presidential nominee was supposed to have stationed senior staff in battleground states, moderated his fiery message to attract new supporters and begun raking in big money.
Instead, he's spending more time right now picking fights and settling scores than delivering a message that might help draw voters.
Five long weeks since he defeated his last remaining GOP rival, Republicans fear the New York billionaire has squandered his head start. As Democrat Hillary Clinton eyes her party's nomination, Trump's campaign has been roiled by infighting, his battleground strategy is lagging and his fundraising operation is barely off the ground.
"I am getting bad marks from certain pundits because I have a small campaign staff. But small is good, flexible, save money and number one!" Trump insisted Monday on Twitter.
Some would-be Republican supporters also fear his unwillingness to budge from a flame-throwing formula targeting immigrants and Muslims that worked so well in the GOP primary.
Case in point: Trump's recent comments about the Mexican heritage of the judge presiding over a case against his now-defunct Trump University. The Republican businessman has refused to back down from his claim that the judge's ethnic background creates a conflict of interest, drawing scorn from across the GOP as well as the legal community.
Republican South Dakota Sen. John Thune said Monday "it's not a good place to be" for Republicans to have to repeatedly explain their presumptive nominee's statements.
"There are I think conversations going on with the campaign, and hopefully that message is being clearly conveyed," Thune said. "But yeah, he's going to have to adapt. This is not working for him. They were inappropriate comments."
Trump also has been slow to adapt to other contours of an expansive general election. Since Texas Sen. Ted Cruz dropped out of the race last month, he has spent precious little time in the battleground states that will likely decide the election.
He has ignored Florida and Ohio, preferring to spend the bulk of the past two weeks in California — a state that hasn't supported a Republican presidential candidate in nearly three decades.
The ongoing rivalry between aides loyal to Trump's campaign manager Corey Lewandowski and to campaign chairman Paul Manafort appears to affect virtually all aspects of the campaign.
Two weeks ago, political director Rick Wiley was fired in the midst of a battleground hiring effort. While the campaign hoped to have senior staff in place across 15 states by June 1, the ex-political director did not finalize a single hire before leaving, according to an aide with direct knowledge of the hiring who was not authorized to speak publicly.
The positions remained unfilled as the factions pushed separate candidates to step in as Trump's political director. Two campaign aides said Manafort appeared to win that battle, getting Trump to hire Jim Murphy, a Republican operative who was involved in Bob Dole's failed presidential campaigns. The aides insisted on anonymity because they were not authorized to discuss the hiring.
But Murphy's hiring was a surprise to others in Trump's inner circle, underscoring the level of confusion.
"Never heard of him," Hope Hicks, the only communications staffer on Trump's payroll, wrote in an email Sunday night after The New York Times reported Murphy's hire.
Lewandowski rejected the idea his candidate is wasting time, arguing that Trump has been delivering a message that appeals to everyone, with numerous trips planned in the coming weeks.
"I think what we're talking about is jobs and security and bad trade deals," Lewandowski said, describing the end-of-May deadline as a false one. He said the campaign is constantly hiring and has state directors all over the country left over from the primary season.
After Clinton delivered a scathing foreign policy speech last week that doubled as a takedown of Trump's qualifications to be commander in chief, Trump responded only with a tweet mocking her reliance on teleprompters — ignoring the former secretary of state's record as the nation's chief diplomat during intensifying international conflicts.
The dysfunction reached new heights Monday during a conference call, first reported by Bloomberg Politics, in which Trump instructed some of his most visible supporters to ignore talking points sent out by his own campaign and to continue focusing on the Trump University case and U.S. District Court Judge Gonzalo Curiel, according to two people on the call.
The memo warned supporters not to speak about the case, because it concerned Trump's business ventures. But Trump said he "absolutely wants us to talk about the case," said one participant, who spoke on the condition of anonymity because the person was not authorized to discuss a private call.
Barry Bennett, a Trump adviser who was also on the call, described the disagreement as a "communication breakdown." He said Trump told his supporters his attacks against Curiel had "nothing to do with skin tone, it's about his bad judicial work."
Trump's slow start with fundraising also has sparked widespread concern across the party.
Trump and the Republican National Committee spent weeks hashing out a money-raising plan after he became the presumptive nominee and stopped funding his White House bid largely with his own fortune.
Yet starting from scratch has been a slow process.
Trump held a small donor gathering ahead of a May 24 rally in Albuquerque and a large fundraiser the next day at the Los Angeles home of Tom Barrack, a good friend and fellow real estate investor. He peppered the rest of his California primary swing with smaller financial events, said Steven Mnuchin, Trump's national finance chairman.
By comparison, Clinton and her top surrogates have hosted some 17 California fundraisers since May 1 alone.
It has taken Trump several weeks to get new large-scale events on the books — although five in Texas and New York are planned for the coming weeks — leaving some of his fundraisers scratching their heads about his lack of urgency.
Rick Hohlt, a Washington lobbyist who has raised money for GOP presidential nominees since 1981 and plans to help Trump, said the campaign's propensity for planning only two weeks ahead poses "a challenge for organizing some of these bigger fundraisers."
Still, he said the candidate "may be right" about his ability to do more with less.
Terry Sullivan, Marco Rubio's former campaign manager, suggested Trump's greatest challenge is his inability to craft a message that appeals to voters beyond his loyal base.
"Trump is a political one-trick pony. He can really excite his base by doing the same trick over and over, but after the rest of the voters have seen it for the 73rd time, they're still not amused," he said.
