Cohen abandoned the suits late Wednesday as he continues to fight to recover documents and electronic files seized from his home, office and hotel room last week by federal authorities as part of what appears to be a broad criminal investigation into his conduct.

"The decision to voluntarily discontinue these cases was a difficult one," Cohen's attorney David Schwartz said. "We believe the defendants defamed my client, and vindicating Mr. Cohen's rights was — and still remains — important. But given the events that have unfolded, and the time, attention, and resources needed to prosecute these matters, we have dismissed the matters, despite their merits."

The dossier claims that Cohen met with Russian operatives somewhere in Europe, including Prague, to attend a meeting to "clean up the mess" created by public disclosures of other Trump associates' reported ties to Russia.
