Washington (CNN) House Speaker Paul Ryan railed against Russia for interfering in American elections, saying Tuesday that he's "more than happy" to consider additional sanctions against the country following last week's indictment of Russian agents who allegedly hacked Democratic email accounts and servers.

The speaker, however, declined to endorse further protections for the special counsel's investigation or criticize a House Republican report that, in contrast to US intelligence agencies' findings, said Russian President Vladimir Putin's actions were not aimed at helping President Donald Trump's candidacy.

"Those GRU officers, I've already seen the intelligence, they were the people that conducted this cyberattack on our elections. We already put in place sanctions," Ryan told reporters during a news conference. "If the foreign affairs committee or the financial services committee and the Senate Banking Committee think that there are other sanctions that we have not yet placed upon Russia, I'm more than happy to consider those."

Ryan's comments come a day after Trump's meeting with Putin in Helsinki, Finland. During a news conference following their meeting, Trump declined to endorse the US intelligence community's assessment that Russia interfered in the 2016 election over Putin's denial. Trump also took jabs at special counsel Robert Mueller's investigation into election interference, repeating his claim next to Putin that the investigation was a "witch hunt."

Ryan declined to say whether Congress should do more to protect Mueller.
