President Donald Trump faces accusations of using taxpayer money for political advertising, according to a New York Times report. Data from AdImpact shows more than $1 million spent on the ads. Democratic lawmakers Jamie Raskin and Laura Whitesides have written letters demanding answers about the spending. Some Republicans have also criticised it. Senators John Thune and John Kennedy raised concerns about the use of public funds. The White House defended the ads as public service announcements. It says they inform the public about government programmes. Critics call that explanation a cover for self-promotion. Federal law limits the use of public funds for political purposes. The dispute adds to ongoing debates about government spending and accountability. Congress may hold hearings on the matter. The White House has not released a full breakdown of the ad costs. Watchdog groups say they will file complaints if the spending is found to breach federal election rules.
