Republican Eric Flores has conceded his bid against Democratic Congressman Vincente Gonzales in Texas' redrawn 34th District, he announced on social media.

This marks the second Republican to concede tonight in a district redrawn to favor Republicans in Texas, following Alex Mealer in Texas' 9th District.

ABC News has not yet projected either race.

Democratic candidate Adam Hamilton, a pastor, is projected to defeat Republican Sen. Roger Marshall and flip the Senate seat.

This the first time Kansas has elected a Democratic senator since 1932.

Democrat Rob Sand will defeat Republican Zach Lahn, flipping the seat to Democratic control for the first time in 20 years.

Sand, 44, campaigned on his record as the state auditor and built trust with voters as the only Democrat elected to statewide office. He ran on an anti-corruption platform with the slogan to help Iowa become "not redder or bluer, but better and truer."

Democratic Rep. Robert Garcia, the ranking member of the House Committee on Oversight and Government Reform, put out a statement minutes after news that the Democrats would regain control of the House.

Garcia's office said he has "vowed to take on the Trump Crime Family, corporate corruption, DHS and ICE abuses, and the cover-up of the Epstein files."

“Lawyer up," the congressman said in a statement.
