(CNN) Republicans tasked with keeping control of the House of Representatives released their first round of nationally backed challengers on Friday, outlining the 11 candidates they believe have the best chance of winning in the nation's most competitive races.

The weight of the Republican Party is now on these candidates' shoulders, given that operatives on both sides of the aisle believe that Democrats, using the national angst caused by Donald Trump's presidency, have a good chance to take back the House in November. These candidates, now part of the so-called "Young Guns" program at the National Republican Congressional Committee, will benefit from increased access to top fundraising circles, more advice from national operatives and on-the-ground help that could be key come November.

The list includes a range of candidates, including some looking to win open seats that are currently in Republican control and others looking to flip seats currently held by Democrats.

Four of the candidates find themselves in races that CNN has rated as toss-ups , the most competitive in the country.

In California, the NRCC is backing former state Assemblywoman Young Kim, who is looking to hold retiring Rep. Ed Royce's 39th Congressional District seat, and in Minnesota, the group is backing St. Louis County Commissioner Pete Stauber, who is trying to turn the state's 8th Congressional District red after three terms under Democratic Rep. Rick Nolan.
