What to watch for during Joe Biden’s first impeachment inquiry hearing

House Republicans hold their first impeachment hearing Thursday, to start publicly making their case after struggling for months to tie President Joe Biden to his son’s foreign business dealings and to corral support inside the GOP conference for impeachment.

Their first hearing, however, isn’t being used to unveil any new evidence or witness testimony, and the trio of witnesses testifying aren’t involved in the Hunter Biden criminal investigation.

Still, Thursday’s hearing – which is before the House Oversight Committee – will lay the groundwork for the battle lines over the GOP-led impeachment inquiry, which has been ramping up with more subpoenas and the release of new documents. Republicans to date have not uncovered evidence showing Joe Biden receiving any money from his son’s business endeavors, and they argue the impeachment inquiry puts them in the best position to obtain the documents they’re seeking.

Democrats counter that Republicans haven’t found evidence linking the president because it doesn’t exist, and charge that the whole impeachment endeavor is an exercise to muddy the waters for former President Donald Trump and the four indictments he’s facing.
