WASHINGTON — A pair of groups supporting President Trump say they raised $30 million last year, then spent tens of thousands of those dollars at the Trump International Hotel here and on payments to a few Trump loyalists like the former campaign manager Corey Lewandowski and the former Milwaukee County sheriff David A. Clarke Jr., according to new campaign finance reports and news reports.

Of the millions raised, at least $1 million came from a coal company that has gained extraordinary access to the Trump administration to push for pro-coal policy changes.

The campaign finance reports shed light on a network of groups that were formed to support Mr. Trump, but have spent less than other groups bolstering his agenda, while steering money to the president’s businesses and his most ardent surrogates.

One of the groups — a “super PAC” called America First Action — spent nearly $33,000 at the Trump International Hotel, primarily on events for donors, and paid tens of thousands of dollars each to Mr. Lewandowski; Brad Parscale, a digital strategist for Mr. Trump’s campaign; and Katrina Pierson, a campaign spokeswoman. Those figures were revealed in a report filed on Wednesday with the Federal Election Commission, which shows that the group raised $4 million last year.
