HOLLYWOOD, Florida: Donald Trump’s chief lieutenants told skeptical Republican leaders that the party front-runner has been “projecting an image” so far in the 2016 primary season and “the part that he’s been playing is now evolving” in a way that will improve his standing among general election voters.

The message, delivered behind closed doors in a private briefing, is part of the campaign’s intensifying effort to convince party leaders that Trump will moderate his tone in the coming months to help deliver big electoral gains this fall, despite his contentious ways.

Even as his team pressed Trump’s case, he raised fresh concern among some conservatives by speaking against North Carolina’s “bathroom law.”

Trump also came out against the federal government’s plan to replace President Andrew Jackson with the civil-rights figure Harriet Tubman on the $20 bill.

Separately, Trump said his wife wishes he would stop tweeting.

Melania Trump was asked Thursday on NBC’s “Today” show what habit she wishes he would give up. “Let’s see,” she said, pausing. “The tweeting.”

Trump’s approach to Twitter has been as unorthodox as his presidential campaign: Unpredictable and unfiltered, sometimes brilliant and occasionally typographically challenged. He has celebrated the support of scores of accounts on the social media service that appear almost solely dedicated to him.

But Trump’s habit has also come with collateral damage— mostly because of the billionaire’s penchant for elevating the comments of his fans to his 7.7 million followers, oftentimes without apparent concern for the source.

He has twice cited an account called WhiteGenocideTM. Many of the accounts with which he interacts use hazy identities or images of models widely circulated on the Internet.

Whoever these mysterious users are, they sometimes provide Trump with information that migrates into his social media assertions, campaign speeches and media interviews.
