Donald Trump has been refuting reports about his campaign links with Russia for months.

On Monday, the president took it one step further by changing his Twitter banner to include one of his recent tweets.

"Director Clapper reiterated what everybody, including the fake media already knows- there is "no evidence" of collusion w/ Russia and Trump," the president proclaimed in the account's main picture, which shows the president surrounded by dozens of people in the Oval Office giving a thumbs up.

The tweet was in reference to testimony at a Senate Judiciary subcommittee by former Director of National Intelligence James Clapper.

Mr Clapper said he stood by past assertions that he had not seen evidence of collusion between the Trump campaign and Russia but also declined to comment on classified matters.

The hearing focused on former national security adviser Michael Flynn's ties to Moscow and allegations that Russia meddled in the 2016 US election.

Although the tweet was later removed from the picture, social media users were quick to mock the change to the banner, with many highlighting the fact it did not appear correctly on many devices.
