violated the rule of completeness or whether the portions the jury heard provided undue emphasis. Fed.R.Evid. 106; see United States v. Binder, 769 F.2d 595, 600 (9th Cir.1985).
We reverse all convictions. We find it unnecessary to address most other issues raised by the defendants. We address two issues that might be raised in a new trial.
II. Vindictive Prosecution
The Shayestehs argue that the three money-laundering charges in the superseding indictment should not only be reversed, but must also be dismissed for vindictive prosecution. The proper standard of review for vindictive prosecution is unsettled. United States v. Montoya, 45 F.3d 1286, 1291 (9th Cir.) (“The court has variously applied abuse of discretion, clearly erroneous, and de novo standards.”), cert. denied, — U.S. -, 116 S.Ct. 67, 133 L.Ed.2d 29 (1995). We need not clarify the standard because even upon de novo review, the district court properly denied the motion.
A prosecutor violates due process when he brings additional charges solely to punish the defendant for exercising a constitutional or statutory right. Bordenkircher v. Hayes, 434 U.S. 357, 363, 98 S.Ct. 663, 668, 54 L.Ed.2d 604 (1978). To establish a claim of vindictiveness the defendant
must make an initial showing that charges of increased severity were filed because the accused exercised a statutory, procedural, or constitutional right in circumstances that give rise to an appearance of vindictiveness.
United States v. Gallegos-Curiel, 681 F.2d 1164, 1168 (9th Cir.1982) (emphasis added). The prosecution then has the burden to show a non-vindictive reason for bringing the charges. Id.
The Shayestehs allege first that the government brought the additional charges to punish them for refusing to accept a plea bargain. During plea negotiations, however, prosecutors may threaten additional charges and may carry through on this threat. United States v. North, 746 F.2d 627, 632 (9th Cir.1984), cert. denied, 470 U.S. 1058, 105 S.Ct. 1773, 84 L.Ed.2d 832 (1985). This action alone does not violate a defendant’s due process rights, nor does it create a presumption of vindictiveness. See United States v. Goodwin, 457 U.S. 368, 380-81, 102 S.Ct. 2485, 2492, 73 L.Ed.2d 74 (1982). The further allegation that the charges were filed because the defendants had moved to suppress evidence is also insufficient to create a presumption of vindictiveness. See id. at 381, 102 S.Ct. at 2493 (“Defense counsel routinely file pretrial motions to suppress evidence ____ It is unrealistic to assume that a prosecutor’s probable response to such motions is to seek to penalize and to deter.”).
Even if there had been a presumption, the government has overcome it by explaining the timing of the charges filed, its discussions with defense counsel and its consultations with the Department of Justice regarding the propriety of money-laundering charges. We hold that there was no governmental misconduct and that the money-laundering charges need not be dismissed.
III. Searches and Seizures
The Shayestehs contend that the district court should have suppressed evidence seized in several searches. We affirm the district court’s admission of evidence seized in the search of the warehouse and Galleria. The search of the apartment, however, was unreasonable. On a new trial, the district court will consider whether any evidence was tainted by that search.
A. Warehouse and Galleria
The Shayestehs argue that the search warrant for their store and warehouse was over-broad. The warrant allowed seizure of all 857 Iranian-origin rugs (worth several million dollars) in the warehouse and all documents relating to the “purchase, importation, and distribution of Iranian-origin carpets.” The Shayestehs argue that the warrant should have been limited to seizure of the approximately 200 carpets,3 and their accompanying documents, that had been marked to identify

Only 114 of these were found during the search.
