Hypothetical and real together in a sentence.

The sentence below is based on the current US politics. Context: The house passed the two articles of impeachment against the president to the senate. In order for witnesses to be testified in the senate, it needs the support of the senators with the majority of the votes.

“If there are witnesses, they would be testified in the senate”. This is a quote from a democratic senator. Now here is my understanding.

When I looked at this sentence, it’s definitely not matching the second conditional sentence structure. Otherwise the sentence would read, ‘‘If there were witnesses, they would be testified in the senate.” To my understanding the original sentence is absolutely correct and is really not second conditional. It is mixed conditional. The first part, ‘if there are witnesses’ shows that there is a real possibility that there are witnesses. That’s why it’s in present form. The second part, ‘they would be testified in the senate’ is a hypothetical sentence and that’s why ‘would’ is used in the sentence. Do you think I am understanding it correctly? Please help.
