Sen. Dean Heller's (R-NV) Las Vegas office was broken into over the weekend, according to several reports.
Neither the Las Vegas Police nor Heller's office would provide KLAS-TV with any comments regarding the supposed note or its contents.
Police say that no items were taken.
Heller is also the only GOP senator up for re-election in 2018 in a state that Trump lost, making him one of the most vulnerable Republicans in the next election. The preliminary investigation by patrol officers determined that a burglary did not occur to the main building or to Senator Heller's office.More news: Now Two Tropical Waves Tracking Across the Atlantic
An anonymous source told Las Vegas' 8 News Now that someone left a threatening note for Heller during the break-in. Authorities could not confirm whether a note was left.
Sen. Heller has been in the national spotlight recently because he's considered a possible swing vote as Republicans try to pass their health care bill.
