evidence: A Florida man was arrested Wednesday in connection with threats to kill Rep. Eric Swalwell, D-Calif., and his children. [...] Shapiro left other voicemails that appeared to refer to allegations tying Swalwell to a suspected Chinese intelligence operative, according to the complaint. They repeatedly refer to "a Chinese spy" and "Fang Fang," it says. The House Ethics Committee last year ended its investigation into Swalwell, dating to 2021, over allegations that he had ties to a suspected Chinese spy Christine Fang.
