2024 Election Security Incident Explorer
Explore the Brennan Center's later tracker of at least 227 bomb threats reported from November 5 through November 9, 2024, plus an official Hamilton County suspicious-package response that is counted separately. The map shows 110 source-linked counties; 66 additional threats reported only at statewide grain remain in the totals without being assigned to a county.
The tracker compiles public reports, may not be exhaustive, and is not an official FBI roster. Incident records and election results remain separate datasets; the optional county-FIPS overlay is geographic context only and does not allege a relationship, fraud, misconduct, altered votes, or an incorrect outcome.

Where the 227 figure and mapped counties come from
The FBI confirms threats occurred but does not publish a national count or county roster. The 227 figure comes from the Brennan Center's later tracker of public reports, which says it may not be exhaustive and is not an official FBI list. Its 66 threats without a named county stay in totals but are not placed on county polygons. Reviewed official state and county records add detail where available, including a separate Hamilton County suspicious-package response that is not added to the bomb-threat total.
FBI Statement on Bomb Threats to Polling Locations
Federal Bureau of InvestigationThe FBI statement confirms bomb threats to polling locations in several states and says none had been determined credible at the time of publication, but it names no state or county. It cannot support a county map row by itself. A manual browser save of the official page was archived on 2026-07-13 after ordinary public access; companion presentation assets are omitted because the HTML contains the full statement and canonical URL.

Letter to ODNI, CISA, and FBI Regarding Election Interference
United States SenateThe congressional letter states that at least 67 polling locations in 19 counties across Arizona, Georgia, Michigan, Pennsylvania, and Wisconsin received threats. Its footnote attributes that figure to NBC News and Reuters rather than to a disclosed federal incident roster, so it is national context and a cross-check, not the county normalization source.

Election Day bomb threats overwhelmingly targeted Democrat-leaning counties
NBC NewsThis is a structured capture of a supplemental news compilation, not an official incident roster. The article reports 67 locations in 19 counties, but its accessible embedded table exposes 18 county rows totaling 66 under a column labeled Threats. Milwaukee is named in the article prose without a separately exposed count. The normalized registry therefore maps Milwaukee with an unknown county count and preserves the article's 67-location national figure as context rather than forcing county totals to equal it.

2024 Election Bomb Threat Tracker
Brennan Center for JusticeThe Brennan Center says this tracker is based on its research of publicly available information and may not be exhaustive. It is a later public-source compilation, not an official FBI roster. Statewide-unspecified rows are retained in totals without assigning them to a county.

ScopeUnited States
Mapped counties110
County not specified66 bomb threats
Affected locations / precinctsNumber of affected election facilities not specified; 1 election office affected; At least 14 known polling locations affected; 6 voting precincts affected
Bomb-threat and other incident countsAt least 227 reported bomb threats documented; 1 additional bomb-threat record has no published count; 1 non-bomb-threat security incident tracked separately
Bomb-threat counts are messages or reports, not necessarily unique disrupted places: one message can name several facilities, and sources may count polling locations, precincts, election offices, or tabulation sites differently. Other official security incidents, such as suspicious-item responses, are identified separately and never added to bomb-threat totals. This report keeps those units separate, preserves statewide counts whose counties were not named, and never turns an unknown count into zero.
Summary by state
Bomb-threat totals and other security incidents stay separate from mapped-county counts.

data/az-2024-election-day-security-pima-source-extract.jsonOpen source FBI Statement on Bomb Threats to Polling Locations
The FBI statement confirms bomb threats to polling locations in several states and says none had been determined credible at the time of publication, but it names no state or county. It cannot support a county map row by itself. A manual browser save of the official page was archived on 2026-07-13 after ordinary public access; companion presentation assets are omitted because the HTML contains the full statement and canonical URL.
data/fbi-2024-bomb-threats-polling-locations.htmlOpen source Letter to ODNI, CISA, and FBI Regarding Election Interference
The congressional letter states that at least 67 polling locations in 19 counties across Arizona, Georgia, Michigan, Pennsylvania, and Wisconsin received threats. Its footnote attributes that figure to NBC News and Reuters rather than to a disclosed federal incident roster, so it is national context and a cross-check, not the county normalization source.
data/us-2024-election-day-bomb-threats-senate-letter.pdfOpen source Election Day bomb threats overwhelmingly targeted Democrat-leaning counties
This is a structured capture of a supplemental news compilation, not an official incident roster. The article reports 67 locations in 19 counties, but its accessible embedded table exposes 18 county rows totaling 66 under a column labeled Threats. Milwaukee is named in the article prose without a separately exposed count. The normalized registry therefore maps Milwaukee with an unknown county count and preserves the article's 67-location national figure as context rather than forcing county totals to equal it.
data/nbc-2024-election-day-bomb-threat-county-compilation.jsonOpen source 2024 Election Bomb Threat Tracker
The Brennan Center says this tracker is based on its research of publicly available information and may not be exhaustive. It is a later public-source compilation, not an official FBI roster. Statewide-unspecified rows are retained in totals without assigning them to a county.
