He stated it in an interview to Voice of America.
"I think today we shall follow the Congress closely. Extremely critical resolution on Ukraine, which Congress passed in September was adopted unanimously. This means that there was not a single American legislator who would act against it. This means that there is an extremely deep concern in Congress regarding what is happening in Ukraine. In Congress, there is talk of sanctions against Ukrainian officials, as it was not a year or two ago. I just hope that Kyiv understands and accepts this as a reflection of deep concern," said the analyst.
Pfeiffer reminded that the U.S. has repeatedly said that progress in Ukraine's relations with the U.S., as well as the progress in relations with the EU will depend on the democratic progress in Ukraine.
"That's why I'm concerned about new charges against Tymoshenko. Given the previous violations of the rule of law in the previous case against her, I think that they will not contribute to improving the relations between Ukraine and the EU and the U.S.," said Pfeiffer.
