Trump may be regretting this tweet about 'Crooked Hillary' right about now

"Not fit!" Trump tweeted on July 6.

U.S. President Donald Trump's old tweets about classified information may come back to haunt him amid reports the president shared classified information with Russian officials last week.

The Washington Post reported on Monday that Trump had shared highly classified information with Russian Foreign Minister Sergei Lavrov and Ambassador Sergey Kislyak during their meeting last week, possibly imperiling diplomatic relations with the country who provided it. The information Trump shared is said to have carried the highest degree of classification and was tightly guarded, even within the USA government. No proof ever emerged of a successful hostile foreign breach of her account, then-FBI Director James Comey said at the time.

The Democratic National Committee said in a statement that Russian Federation "no longer has to spy on us to get information" because Trump will tell them whenever they ask.

There has been a legal debate on whether Mr Trump was allowed to declassify the information he leaked in order to share it with Russian officials, but Ms Navarro mocked the "enablers" for using that as an excuse for Mr Trump being "clueless" or "incompetent".

WATCH: H.R. McMaster says he stands by his comments that a Washington Post story about president Trump leaking classified information was false. "Humanitarian reasons, plus I want Russian Federation to greatly step up their fight against ISIS & terrorism", he wrote in combined tweets.

Trump's meeting with the Russians came just one day after he fired Comey as Federal Bureau of Investigation director.

Several Republican lawmakers were also critical of the misuse of classified information.

Trump's tweets Tuesday lack any mention of whether the information he shared was classified.

Revealing it "jeopardized a critical source of intelligence on the Islamic State", according to the Post - specifically by giving the Russians enough information about the nature of the source to easily identify who or what it is.
