Texas, said Wednesday Republican lawmakers and federal investigators will continue digging into questions about former President Joe Biden’s mental faculties while he was in office Cornyn also highlighted allegations that those around Biden covered up his cognitive decline and said the ongoing probes could result in criminal prosecutions.

WASHINGTON (AP) — Nearly six months after Joe Biden left the White House, Senate Republicans are still scrutinizing his presidency, kicking off the first in what’s expected to be a series of congressional hearings this year on his mental fitness in office.

Republicans on the Senate Judiciary Committee used a hearing Wednesday to air questions about use of the autopen in the Biden administration.

A proposal by Senate Republicans would adjust the pace at which some crucial home energy efficiency and electric vehicle tax credits are phased out in timelines different from what House Republicans proposed in the multitrillion-dollar tax bill they passed last month.

Senate Republicans’ tax bill would eliminate federal taxes and regulations on short-barreled rifles, short-barreled shotguns and silencers as well as preempt state or local licensing requirements in a win for gun-rights advocates.

If enacted, Republicans’ draft legislation would mean that President Biden’s signature climate legislation would effectively be neutered.
