Three Democratic senators should be investigated for threatening to withhold U.S. aid from Ukraine last year if its prosecutor did not help with Robert Mueller's Russia investigation, Sen. Rand Paul, R-Ky., said Monday.
"The only thing consistent about the whole discussion of people threatening Ukrainian aid is that everybody seems to be doing it, on both sides," Paul told "Fox and Friends" on Fox News.
"Joe Biden threatened the aid and then three senators wrote a letter to the Ukrainian government, and they said if you don't continue investigating Trump, and help the Mueller investigation, we may pull back on your aid.
"We can't have two standards," Paul added. "Democrats get to threaten Ukrainian aid and nothing happens to them.
"Now they want to impeach a president over this?"
Paul was referring to a May 2018 letter written by Democratic Sens. Robert Menendez, N.J.; Dick Durbin, Ill. and Patrick Leahy, of Vermont. to Ukraine's prosecutor at the time, Yuriy Lutsenko.
The senators cited a report in The New York Times that Lutsenko's office had "effectively frozen" inquiries into four cases on the consulting work of former Trump campaign manager Paul Manafort for Ukraine that was being probed by Mueller's team.
"If these reports are true, we strongly encourage to reverse course and halt any efforts to impede cooperation with this important investigation," the senators wrote.
In 2015 Biden pressured Ukraine in 2015 to fire Lutsenko's predecessor, who had been investigating a state-run gas company with ties to Hunter Biden.
"In the end, it's going to be seen by the American public as very partisan," Paul told Fox News of the House impeachment inquiry of President Donald Trump. "If the House sends it over, I think it will be voted down in the Senate."
