A senate committee voted along party lines to issue a subpoena as part of the Republican-led investigation into the Ukrainian energy firm that hired former Vice President Joe Biden's son, Hunter Biden.
The subpoena is one of several steps Senate Republicans are taking to ramp up probes related to the Obama administration and Biden, the presumptive Democratic presidential nominee who will likely challenge President Donald Trump in the 2020 election.
Democrats denounced the investigation as a partisan effort to help Trump's reelection bid.
It's pay back time. Never forget, never forgive. An Eye for an eye and a subpoena for a subpoena. Just a thought.
