I let my anger at a baseless investigation w evidence to the contrary get me to incorrectly say Congress needs probable cause for a subpoena. Courts only require a Congressional subpoena be relevant to a legitimate inquiry (which I doubt it is for Biden's bank records). But they should have more than a desire to hurt a political opponent & they don't. That's why democracy is in danger. Thanks to @weissmann11 for reaching out to calm me down and get me to correct this.
