Tarrant County reported more than 20% of its mail-in ballots could be defective and may need to be replicated, which could delay election results.

In a statement late Tuesday, the county said 11,000 of the 69,941 mail-in ballots received as of 9 p.m. are expected to be rejected by their voting machines. The announcement comes after elections officials reported issues with counting mail-in ballots and held an emergency meeting on Monday to bring in extra volunteers to manually go through defective ballots.

"Tarrant County Elections remains committed to providing the Ballot Board all resources necessary to complete an accurate count of votes, which reflects the intent of Tarrant County voters. The ballots affected by the barcode error will continue to be properly duplicated, and every vote cast will be counted as each voter intended," the statement read.

State law allows mail-in ballots in counties with populations over 100,000 to be counted after the polls close on the last day of in-person early voting. But Tarrant County officials ran into problems when its election scanners rejected the barcodes on thousands of mail-in ballots.

The statement did not say when the counting of these mail-in ballots might be completed.
