Sen. Lindsey Graham has called for a federal probe of Pennsylvania ballot fraud.

As Senate Judiciary Committee chairman, the South Carolina senator has received a copy of Pennsylvania postal worker Richard Hopkins' ballot fraud charge.

Graham carried Lexington County in a successful race against Democrat Jaime Harrison Nov. 3.

Hopkins' affidavit was cited in Attorney General William Barr's order to investigate any allegations of voter fraud or ballot tampering.

Hopkins alleged a supervisor tampered with mail-in ballots.

House Democrats claimed he recanted but Hopkins released a video denying it this week.

Hopkins charged Erie, PA, Postmaster Robert Weisenbach and a supervisor changed the postmark dates on ballots and sent them to election officials.

Weisenbachhas denied this, according to the Erie Times-News.

Hopkins signed a sworn affidavit, according to Trump campaign officials, and was questioned extensively by USPS investigators.

The Postal Service Inspector General declined to comment as the investigation is still open.

President Donald Trump's campaign has filed more than a dozen lawsuits in at least 5 states.

The President claims he would have won were it not for “illegal” votes counted in several states that he lost or where he is trailing.

In Pennsylvania, the campaign has challenged the state Supreme Court ruling allowing election officials to accept mail-in ballots up to 3 days after the election if they were postmarked by Election Day.

The Trump campaign has sued over:

- Observers being blocked from witnessing ballot counting in Pennsylvania.

- The Republican secretary of state telling counties that voters whose absentee ballots were rejected could cast a provisional ballot.
