Among those worried is Republican National Committee Chair Ronna McDaniel, who recently told the president she was concerned his ads were not on television in states such as Michigan and Florida where Biden was blanketing the airwaves, according to people familiar with the conversation. The president shared the concern, according to the officials, who spoke on the condition of anonymity to discuss internal deliberations.

The decision to slash spending has been ordered by Trump’s new campaign manager, Bill Stepien, who has been restructuring the budget since taking over the campaign operation in July, after it had already spent nearly $1 billion.

Stepien has told others that cutting the ad budget was necessary because it was impossible to cut other spending, such as staffing or a campaign headquarters. He has described facing difficult choices, as he tries to save considerable money for the final 30 days before the Nov. 3 election.
