Trump virtually demanded his attorney general, Jeff Sessions, undertake an investigation of Obama and officials in that administration. Trump tweeted Wednesday. "Why didn't Obama do something about the meddling?" Why aren't Dem crimes under investigation? Trump tweeted on Monday evening.
Trump later reissued his tweet with "Sessions" spelled correctly.
Mr Trump has previously criticised Mr Obama for not doing more to prevent Russian meddling.
Speaking on condition of anonymity, officials said a "task force" has been set up to address potential meddling in the 2018 congressional elections and work is underway to introduce more sanctions in response to Moscow's 2016 campaign. Trump later said he thought the Russian leader was earnest when he denied any election meddling. "It's also very clear that it didn't have an impact on the election, and it's also very clear that the Trump campaign didn't collude with the Russians in any way for this process to take place". Over the summer, Trump expressed anger that Sessions - an early supporter of his presidential campaign - had recused himself from the investigation and said he would have picked someone else if he had known that would happen.

The enlarged river at Cincinnati crested at about 55.4 feet Tuesday night, which is about 3.5 feet over flood stage. In Homer in eastern Champaign County there was a report of about 5.3 inches of rain over the past two days.
During testimony before the House Judiciary Committee, Sessions pushed back against calls that a special prosecutor be appointed to look into the FBI's handling of the Clinton email probe.
White House press secretary Sarah Huckabee Sanders said Tuesday that Trump has been "extremely tough on Russian Federation", pointing to a boost in US military spending, energy exports to eastern Europe, Trump's upholding of Obama-era sanctions against Russian Federation and the USA decision to provide Ukraine with lethal weapons, including anti-tank missiles.
In another tweet, Trump said, "I have been much tougher on Russian Federation than Obama, just look at the facts". He also has yet to enact sanctions against the Kremlin, which Congress overwhelmingly approved previous year.
White House press secretary Sarah Sanders is scheduled to field reporters' questions for the first time in a week on Tuesday.
