Candidates running for House and Senate offices increased campaign spending on security by more than 500 percent between the 2020 election and the 2022 midterms, a new Washington Post analysis of filings with the Federal Election Commission found, a measure of the extraordinary rise in threats against elected officials in recent years and the country’s increasingly volatile political climate. The steep increases came as changes in federal campaign finance rules made it easier to spend campaign dollars on security, a recognition of the nation’s changing threat outlook for elected officials. Spending by House and Senate candidates rose from $1.3 million to nearly $8 million in that time, the analysis found. The Post also found that House members have spent more of the annual governmental allowance they are given to fund their offices on security, with such spending rising from about $675,000 in 2020 to $1.2 million in 2022.
