WASHINGTON — President Trump’s campaign and the Republican National Committee together spent more than $9 million on polling, digital ads and fees paid to Trump-owned properties in the last three months of 2019, according to filings with the Federal Election Commission released on Friday.

The filings detail how the Trump campaign, the Trump Victory committee, a third entity called the Trump Make America Great Again Committee and the national party committee spent their cash from October through the end of December. Together, they previously reported raising $154 million over those months, and closed the year with $195 million in cash on hand.

The Trump apparatus has raised an outsize sum, but it has faced questions about how, exactly, it is spending its reserves. Even though he is not funding his own bid this time around, Mr. Trump has repeatedly grilled his advisers about where and how they are spending money.

According to a New York Times analysis, the biggest expenditure in the final three months of the year was on digital advertising. From October to December, the campaign spent more than $6 million on digital ads. The T-MAGA committee spent another $3.2 million on digital ads.
